Bolt Thread Size (Damn Metric ****)
I think this might be metric bolts because they dont appear to be SAE.
I am puzzled what they are referring to. I bought a used Makita table saw at a garage sale. It needed a few repairs which I took care of. I got a downloaded PDF file from their Makita website to help me determine what went where. I got it all together and it works except the rip fence is missing a bolt that makes it clamp sloppily. My parts can does not have anything that will fit, so I'm off to the hardware store later today. The parts list in that PDF file show this bolt as "Hex Bolt M6X16". WTF is that? I am assuming the "M" means metric. Is that correct? I am assuming 6X16 means 16 threads per inch. (that looks about right), but what is the "6"? 6 centimeters long, or is it 6cm thick? There's a number missing either way...... Now looking at it in SAE terms, it's about 1/4" thick, fine threaded, and 1/2 to 5/8 inches long, and the head is roughly 3/8" hex. Damn I hate metric ****...... I wish I had been born 100 years sooner so I'd never have to get frustrated by this metric crap. I was born in America, that means I should be speaking English, and using inches and feet, not speaking a foreign language or using goddamn metrics from countries that dont know how to measure things. Yep. metrics are one of my top pet peeves that really **** me off........ At least they dont have the rip fence ruler in metric, or I would have not bought the saw. At my age, I am too old to change to metrics anyhow. Mark |

Mark You might find the following helpful http://www.sosmath.com/tables/sae/sae.html http://www.namrick.co.uk/boltspec.asp If we had switched to metric 100 years ago we all would have been better off. :-) You would still be better off if you did it tomorrow. What's the impediment except for guys like the OP. All of your multinationals manufacture things for the rest of the world in metric sizes. Your manufacturing industries would be much more competitive if they turned over to the right side. The only thing that keeps imperial measurements going is a reasonably large domestic market, and that will evaporate in the next few years in the face of foriegn competition (China). |

The missing number is the thread pitch. 6x16 means 6mm in diameter x 16mm long. Thanks for the info, and yeah, it's MM not cm.... So, are all metric bolts the same thread pitch since they dont list it??? It's so much easier to say I need a 1/4" bolt 1" long with 24 threads per inch. I think all metric bolts should be sent back to their own country of origin, and the US governement should ban them in the US. If for no other reason, they are anti-patriotic. America was built with inches, feet, yards and miles.......... |

Nope, with metric, yo don't need to know the thread pits except in a few unusual cases. That is mm, not cm and it is 16 mm long. Damn I hate metric ****......

Yep. metrics are one of my top pet peeves that really **** me off........ Many people feel that way but eventuall we get educated and find that our system is the strange one and metric is sooooo much easier. If the 10mm socket is too small, the 12 mm is too big, you can be sure that 12mm is the right one. No 17/32 to figure out. At least they don't have the rip fence ruler in metric, or I would have not bought the saw. At my age, I am too old to change to metrics anyhow. When I started working at my present employer, we had some imported machines (none made in the US any more) and I had to learn metric. It takes about a day and a half and you realize it is easier to think in bars and millimeters. The medical field has used metric forever. It just makes sense, just like our money system that you like compared to shillings and quid and lira. Of course, we have to change some of our old sayings , like trying to stuff 10 kilos of **** in an 8 kilo bag. Learn it, for it is not going away. |

Thanks for the info, and yeah, it's MM not cm.... So, are all metric bolts the same thread pitch since they dont list it??? Nope... metrix bolts are measured in how far from thread to thread. It will most likely be an M6x1x16, meaning 6mm in diameter, 1mm from thread to thread and 16mm long. It's so much easier to say I need a 1/4" bolt 1" long with 24 threads per inch. Naw... M6x1x16 is just as easy as 1/4"x1 UNC |

People who think that if you work in metric, you have to convert it to English. One of the dumbest arguements agains changing that was ever made. Please tell me why you would want to know what the English measure was for a metric piece of lumber. To find out how it spans studs 16" OC, perhaps? The problem is primarily in having to mix the two and irregardless of the theoretical niceties of metric vis a vis English, there is a history dating back several hundred years that can't be whisked away--if, for nothing else, for those raised using English, despite "book-larnin' " about MKS, it just "ain't natural". As a trained engineer working w/ metric for 30 years, there still isn't the inate "feel" for ordinary day-to-day things in metric measures that there is for English. I just don't think that I'm really putting in 19 l instead of 5 gal so it's "only" 76.5 c/l instead of $2.90 /gal -- no, all I'm thinking is the producers are making a killing at $75/bbl. Similarly, it's going to be d-- near 100 out this afternoon...I don't feel a bit cooler at whatever it is in C and I have to stop and calculate it out rather than "just knowing". And, even as we continue to teach mks in school, the common usage remains (and will remain for the foreseeable future). Also, I don't really agree w/ the argument advanced earlier that there are really that many fewer sizes in metric--in actuality, it seems to me there tend to be more, at least in the smaller sizes where it seems you find stuff every mm. I do agree that the 70s/80s transition period with mismatched fasteners on a single product was an abomination--I had one of them as well. I'm not sure how much it really affects US industry's overall efficiency--as someone else noted, most export sales are and have been metric for quite some time now and a great portion of that production is not in the US anyway. I'm sure there is some affect, but doubt it would make a huge difference in competitive balance if it were to disappear overnight (which of course, it can't owing to all the above historical considerations). |

I really dont understand how it can make more sense. Do you really
think anyone can remember all these numbers? (examples below) a 2X4 board = 5.08 x 10.16 (cm) Why would you make a board 5.08 x 10.16cm? You would make it 5x10. a 1x6 board = 2.54 x 15.24 2.5 x 15 an 8 foot long stud = 2.4384 (meters) 2.5 meters 4x8 foot sheet of plywood = 1.2192 x 2.4384 (meters) 1.2x2.4, or 1.5 x 2.5 Get it? Do you have a problem with buying a 2 liter bottle of Coke? Of course not, it's 2 liters. They don't package and label it as 2.15 quarts bottle. In the same sense, a 10mm bolts is called a 10mm bolt. It's not a ..3937" bolt. It's just a matter of getting used to visualize a quantity or weight of something using metric measurements. |

It's a trick of proportion. We average twice as tall as you guys, so the building standards are based on entirely different numbers. snicker ;- In reality, Canada has evolved to a situation somewhat short of where Europe is. All official weights and measures are MKS (metric), such as surveys, standards etc. Schools teach very little of FPS (Imperial aka "english"). The latest generation can pretty much entirely avoid FPS until they're in the construction industry. Residential construction _itself_ is still using an unchanged system almost identical to yours. 2x4s, 8x2 sheets of construction plywood, 12/16/24" joist spacing etc. We do see sheet goods with metric thickness measurements (eg: 11mm sheathing), and the odd bit of sheet goods (normally not for construction) with metric dimensions - eg: furniture grade plywoods or melamine - about an inch oversize. It may seem confusing, but in practise it isn't. I grew up in FPS, and now I'm equally comfortable in both systems. [Except pascals. I hate pascals. They should use mm of mercury - that I can visualize - it's been around far longer than our metric "conversion".] Given the education system, and another generation, only a few industries will be doing much in the way of FPS, and we'll arrive in a situation where we'll be viewing construction practise in the same way you should be viewing that idiotic penny nail measurement "standard". -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them. |

Besides, why use a second rate measurement system when we could go with a better one. inches, feet yards rods miles (two kinds) and no easy conversions between any of them, while in You forgot fathom, chains, furlong, leagues. And to be offended that the plural for two of those is the same as the singular. There are 11 fathom in a surveyor's chain. Not to mention 2.75 fathoms in a rod. See? It's simple. [I _think_ fathom and chain both pluralize with ".s"] -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them. |

For example, a Canadian car has a speedometer that displays speed in kph (kilometers per hour), the speed limit signs are posted in kph, and the distances on the highway signs are in kilometers. No big deal. You see a sign that says "Toronto -- 100km", you look at your speedometer and see that you're going 80kph, and you know that you'll be there in an hour and a quarter. But I have to mentally compute (by 5/8 for convenient reasonable approximation) to find out I'm actually only about 62 miles away! Naaaah. You're an hour away. Drive faster, you get there sooner; slower, later. Who cares about the distance? -- Regards, Doug Miller (alphageek at milmac dot com) It's time to throw all their damned tea in the harbor again. |

People who think that if you work in metric, you have to convert it to English. One of the dumbest arguements agains changing that was ever made. Please tell me why you would want to know what the English measure was for a metric piece of lumber. To find out how it spans studs 16" OC, perhaps? The problem is primarily in having to mix the two and irregardless of the theoretical niceties of metric vis a vis English, there is a history dating back several hundred years that can't be whisked away--if, for nothing else, for those raised using English, despite "book-larnin' " about MKS, it just "ain't natural". As a trained engineer working w/ metric for 30 years, there still isn't the inate "feel" for ordinary day-to-day things in metric measures that there is for English. I just don't think that I'm really putting in 19 l instead of 5 gal so it's "only" 76.5 c/l instead of $2.90 /gal -- no, all I'm thinking is the producers are making a killing at $75/bbl. Similarly, it's going to be d-- near 100 out this afternoon...I don't feel a bit cooler at whatever it is in C and I have to stop and calculate it out rather than "just knowing". And, even as we continue to teach mks in school, the common usage remains (and will remain for the foreseeable future). Also, I don't really agree w/ the argument advanced earlier that there are really that many fewer sizes in metric--in actuality, it seems to me there tend to be more, at least in the smaller sizes where it seems you find stuff every mm. I do agree that the 70s/80s transition period with mismatched fasteners on a single product was an abomination--I had one of them as well. I'm not sure how much it really affects US industry's overall efficiency--as someone else noted, most export sales are and have been metric for quite some time now and a great portion of that production is not in the US anyway. I'm sure there is some affect, but doubt it would make a huge difference in competitive balance if it were to disappear overnight (which of course, it can't owing to all the above historical considerations). Good valid points about what your are used to. The changeover, if it ever occurs, will not be painless of course but the pain won't last long. In a few years everyone except a few would be wondering why they fought it. England made the change and never looked back. There would remain the problem of matching up metric with stuff built under the English system but it can be done (England for one). Harry K |

You're an hour away. Drive faster, you get there sooner; slower, later. Who cares about the distance? ,,, I guess you didn't take the smiley at face value??? But, strangely enough, some folks _do_ have a yen to know the distance---from my experience I hypothesis it tends to the folks in cities and areas which aren't amenable to straight-line navigation (such as the Eastern US w/ all the windy hills, etc.) that simply consider distances as time. Being in and from an area that is all laid off in sections, we navigate by section line and distances are what is the innate feeling. As my other post notes, it's a case of what one is familiar with, nothing else... |

That's what I recall the mantra being about the time my kids started school--as is typical in the US, however, being no widespread public "mandate", there was no way to get a universal acceptance and the movement floundered. Despite the (more-or-less) common language, there's a big difference between public/government dynamics in the US vis a vis England. I don't foresee a switch in common usage for a long time (TM). Even the campaigns for metric road signs (about as painless as it gets) are all gone afaict. |
