Joseph L. ★★★★★

Finally found machine screws small enough for the delicate camera adjustment plates I’m building. The #4-40 threads are precise and the truss heads sit flush without stripping.

Alexander ★★★★★

Just finished assembling a batch of fixtures and these #4-40 screws seated cleanly without any stripping—the Phillips drive cuts down on cam-out nicely. Having 1,800 pieces means I won't be running out anytime soon, and the 18/8 stainless should hold up well in the damp basement environment.

Natalie R. ★★★★★

These little truss heads fit perfectly into my control panel prototypes, and the stainless steel finish still looks clean after sitting in a damp garage for weeks. I appreciate that they’re non-magnetic too, since my magnetic screw tray doesn’t grab them.
