I had to drill and tap a bunch of blind holes for 8-32x3/4" socket head cap screws. Since I didn't have the cap screws I needed, I bought a box of new ones locally. The drilling and tapping went just fine. When I tried to screw the cap screws into the holes, they acted like they were too big. In fact, that was their problem! I had to run each brand new cap screw through the 8-32 die to remove just a sliver of metal so that the screws would fit into the holes. Once each cap screw was run through the die, they worked just fine. I looked at the box the cap screws came in and on the bottom in very fine print was, "Contents may be made in China, Taiwan, Hong Kong, USA or other countries." At 25 cents per screw, one would think you would get a quality product, not one that you have to rework to make it fit. It wasn't worth taking them back to argue with an unknowning sales girl at the return counter. She wouldn't have a clue what I would be talking about and she would just exchange the unused ones for more of the same. I guess from now on I have to order what I need and not use local suppliers so that I can specify what I need.
