Screws made under MS and NAS aircraft/aerospace standards are generally still made in USA but the types used for trim were long ago outdated and most aviation stuff is phillips head cross recess types anyway. A lot of the old aviation stuff can't be used on aircraft anymore due to a quality standards act back in the 90s that requires the part have manufacturer's code, lot number, and date of manufacture plus a certificate of conformity. Folks try to sell the stuff on flea-pay now and then but I can't use the stuff anymore due to the current rules & regulations. I save it for automotive use now.
