Sofia T. ★★★★★

The hex socket drive made installation on my jig setup so much easier than using a standard slotted screw. These 18/8 stainless steel screws feel solid and haven't shown any rust after a few months in a slightly damp shop.

Elizabeth K. ★★★★★

Just finished assembling a small jig for my workbench and these #4-40 screws threaded perfectly into the tapped holes. The hex socket drive made installation a breeze with my Allen key, and the 18/8 stainless steel feels sturdy enough for repeated adjustments. Exactly what I needed for precision wor

Penelope ★★★★☆

I needed these for a precision assembly and the hex socket drive made installation a breeze. The 18/8 stainless steel feels solid, though the packaging could have been a bit more organized.
