Two identical screws with different thread chamfers.
Two identical screws with different thread chamfers.
(OP)
I have before me two 5/16-24UNFx 3/4 long Hex Head Cap Screws. One has 1 to 1 1/2 threads chamfered off while the second has threads to the end (minimum chamfer). Am I looking at two screws made to different Standards or manufacturer's discretion?
RE: Two identical screws with different thread chamfers.
If you require a point chamfer for commercial fasteners it is a very good idea to explicitly specify (and define) it up front. Point chamfer requirements/options will depend on the specification (if any) that parts are manufactured/purchased to.
