In Reply to: Lock Washers????? posted by Jiles on July 30, 2014 at 08:35:48:
My boss used to work in a Caterpillar engineering group. He said that in that department the use of any locking device be it a lock washer, thread locker, lock nut, etc, was considered a "Band-aid" since it meant the bolted joint was insufficiently designed. In our engineering department we use a lot of high grade hex flange lock nuts but we never use lock washers except in very unique situations. We use hardened flat washers under nearly any screw or nut that doesn't have a built- in flange to allow for a more precise bolt stretch when torqued to a given level. Like you said, it is the bolt stretch and resulting clamp load that keeps things tight. You can drastically improve the integrity of a joint by adding a spacer and using a longer bolt to get more stretch for a given clamp load.
