Jim asks: Hi I have been buying the 10-32 X 1/2" set screws from you, my question is do you have these in 3/8" length? If so, if I place another order for 100 pieces can you send 75- 1/2" length and 25- 3/8" length?

Sorry we do not do assortments.  Each item will need to be ordered and paid for separately while abiding by product minimums.

Hillary asks: What size hex are the coupling nuts? I need some of these for a project. It calls for M4 coupling nuts that are a 12 mm hex

All product specifications/dimensions are located in the item description.

Mike asks: On a lot of your part designations in the description, I see "FT."  Does that me the parts are that many feet long or does "FT" mean something else?

FT= fully threaded parts.  PT= partially threaded.
