Wiki: Spanners
Another one for your perusal and improvement...
==Spanners== ===Open end=== [[image:Open ended spanner 319-4.jpg|thumb]] ===Ring=== [[image:Ring spanner 319-4.jpg|thumb]] Not as prone to slipping off as open end, but usable in less situations. ===Combination=== [[image:Combination spanner 319-4.jpg|thumb]] A combination spanner has 2 different types of driver on the one spanner. Most often these are open and ring, but other combinations are also available. ===Ratchet=== ===Adjustables=== Adjusable spanners are called [[wrench]]es. ===Self adjusting=== [[image:Adj spanner 82-2.jpg|200px]] ===Box spanner=== The forerunner of the socket set. Lighter, cheaper, weaker, and no longer popular. ===Socket set=== [[image:Socket set 198-3.jpg|thumb|Socket set]] Cast steel sockets can apply much more torque and control than open ended spanners, but are more cumbersome and can't always be used. Extension bars enable clearing nearby obstacles. Torque wrenches enable setting bolts or nuts to precise torque. A few different types exist. Deep sockets can be used where bolt threads protrude, and on spark plugs. Sockets come in any of several drive sizes: 1/4" - for very light duty work eg appliance case screws 3/8" - light duty 1/2" - good for a lot of general purpose use, but not big sizes or high torque jobs 3/4" - good for heavy duty work, eg washing machine bearings and tougher items on cars 1" - industrial duty ===Stamped spanner=== [[image:Stamped spanner M12 317-4.jpg]] Most spanners are cast, these ones are stamped from sheet metal. The result is a thin flat spanner with lower weight and strength. They're plenty strong enough for a wide range of tasks, but the thin metal edge makes applying high forces with a bare hand painful. Fine for medium force. Stamped spanners tend to be made from mild steel rather than the tougher rust proof chrome vanadium steel used for most spanners, so should always be stored dry as they rust readily. [[image:Stamped spanner set 416-3.jpg|thumb|Stamped spanner set]] Stamped spanners tend to come supplied with an appliance as manufacture cost is much lower than cast spanners. Whole sets are rarely seen. ===Multispanner=== [[image:Multispanner small 422-2.jpg|thumb|Small multispanner]] A stamped sheet spanner with many different size cutouts around the edges, or a casting with many cutouts. Available in a few well known patterns. These don't give good performance for general DIY use, they're better suited to bikes where the low weight and size is a definite advantage, and they don't see much use. The smallest ones (pictured) are the least friendly to use. ===Basin wrench=== [[image:Basin wrench 318-6.bmp|thumb]] Can undo taps from a greater variety of positions than other spanner types. Useful when working in confined positions. ==Wrenches== Spanners are known as wrenches in American English. Adjustable spanners are usually called wrenches here. ==More torque please== ===Extension tubes=== Fitting steel tube over a spanner to get much more leverage works, but is a known cause of injuries. Where large leverage is needed, a socket is a safer option, with long handles available. ===Impact wrench=== When even more torque is needed, an impact wrench is the best choice. This is much better controlled way to apply high torque than hand tools. ==See Also== * [[Wrenches]] * [[Clamps]] * [[Special:Allpages|Wiki Contents]] * [[Special:Categories|Wiki Subject Categories]] [[Category:Tools]] [[Category:Basics]] NT |

How about some explanation of how nominal sizes relate to actual 'across
flats' distances in the various systems? -- Rod Hypothyroidism is a seriously debilitating condition with an insidious onset. Although common it frequently goes undiagnosed. www.thyromind.info www.thyroiduk.org www.altsupportthyroid.org |

Some stuff needs 1/2 - mainly stuff that's on so tight that a pipe on the end of my 3/8" bar isn't working, so I go for the impact wrench. 3/4" is occasionally needed on commercials and agricultural machinery but I'd not bother using it on anything on a car unless it was being *incredibly* recalcitrant. |

I agree though usually use 1/2 inch If you aim to give a comprehensive breakdown of kit have a look at the snap-on site where they list 1 1/2 and 2 1/2 inch drives and sockets Tony |
