wrote in message ... snip As to the "waste of time issues, you may have a point. If you are employed and earning sixty-five dollars per hour it would be difficult to justify an hour round trip and visit to the local HFT much less an expected return visit to collect the refund as the cost in your time when added to the price of the discount item will likely approach the cost of the brand name gizmo. Cannot agree here with this analogy. Even if one is employeed and earining $1000 per hour it is a very likely chance that he is buying this product during his "Free Time" Free time does not pay. Regardless of the price if you are on free time and not being paid, returning the product for a refund results in you being financially better off providing the cost of the trip, ware, tear, and gasoline to return the product, does not exceed the value of the refund. |

Haven't kept up with the thread. Was using loctite mentioned?

Loctite generally causes more problems than it solves. The need is for getting the fastener tight, not gluing it in a loose position (such as with loctite). To get tight and remain that way, the screw is run in until the head contacts the part to be held and is then turned somewhat further, putting the screw in tension. Due to the large surface area of the thread engagement and the 60 degree angle of the threads, they will gal and seize well before the body of the screw comes under tension. Buy using a high pressure lubricant on the threads,the screw can be turned enough to put it under proper tension and it will hold much tighter than it would dry. The lubricant used must be a high pressure type (Lubriplate, Antisieze, etc.). Something like 3 in 1 oil will not do it. Putting the body of the screw under tension is the same way a lock washer works. Though the screw may not be really tight(due to the galling), the spring pressure of the washer holds the screw under tension preventing it from loosening. In addition, anyone that has worked with black pipe will tell you, the pipe will not seal without the application of Teflon tape or pipe dope before assembly. Pipe dope and Teflon tape is NOT a sealer. It is a lubricant which enables you to tighten the threads enough for the threads to make a seal. The point? Use some anti seize on the screw. |

Fasteners using loctite are not meant to be loose, but tightened to spec.

Due to the large surface area of the thread engagement and the 60 degree angle of the threads, they will gal and seize well before the body of the screw comes under tension. There is galling and there is GALLING. Torquing a fastener to spec is putting it under tension and is what holds it and what torque specs and torque wrenches are for. This causes galling on a microscopic level whichs is acceptable and does not prevent fasteners from being torqued to spec multiple times. This is common with many fasteners of varied materials. Stainless steel IS highly prone to galling, but can still be torqued to spec without lube and without major galling, but it's a crap shoot. When SS really galls, you'll know it. That sucker is welded and will have to be broken to remove. under proper tension and it will hold much tighter than it would dry. The lubricant used must be a high pressure type (Lubriplate, Antisieze, etc.). Good quality lubricants like motor oil, graphite, etc, can provide adequate lubrication. Something like 3 in 1 oil will not do it. Not a great choice, but better than a poke in the eye with a sharp stick. Also, WD40 is NOT a lubricant. Putting the body of the screw under tension is the same way a lock washer works. Though the screw may not be really tight(due to the galling), the spring pressure of the washer holds the screw under tension preventing it from loosening. Lock washers work only partially by tension. The primary locking mechanism is by the washer digging into and deforming the fastener/contact points into a nonslip surface. without the application of Teflon tape or pipe dope before assembly. Pipe dope and Teflon tape is NOT a sealer. It is a lubricant which enables you to tighten the threads enough for the threads to make a seal. You can turn bare pipe threads beyond their max engagement and they will still leak. You can turn bare pipe threads to optimum engagement and they won't seal, but upon adding tape/dope and turning to same level of engagement, sealing occurs. Yes, it is a sealer. And, yes, it is also a lubricant. The point? Use some anti seize on the screw. At the very least, some sort of lubricant is preferred. Even alcohol is better than nothing. OTOH, using no lubricants whatsoever is acceptable practice under required conditions, regardless of the fastener material. Depends on the application. nb |

So could you just use teflon tape? |

On Tue, 02 Jun 2009 15:42:48 -0500, the infamous TD Driver
scrawled the following: I cranked down on that sumbitch as hard as I could, but I'm getting to be an old guy. I was thinking of having SWMBO come out and yell at it some. As someone noted, ya gets what ya pays for. I'll reserve this for thinner stuff and break out hammer and chisels for this piece of work. Here ya go: Use with a 3/8" breaker bar and wrench on the tool shaft http://www.harborfreight.com/cpi/cta...emnumber=93203 Use these longer allens with a wrench on the tool head: http://www.harborfreight.com/cpi/cta...emnumber=96645 And, if you use it only with that blade, try some of this Loctite on the screw: http://fwd4.me/1Hk If the medium strength (blue, 243) doesn't hold, try the red (272) schtuff. -- The only reason I would take up exercising is so that I could hear heavy breathing again. |
