Andrew B. ★★★★★

I needed exact-fit replacements for a jig I've been tweaking, and these 1/4-20 x 3/4" socket heads threaded in perfectly without any binding. The black oxide coating seems well applied, no flakes or uneven spots.

Zoe ★★★★★

The black-oxide finish looks sharp and hasn’t shown a speck of rust after a week of sitting in my damp shop drawer. Slipped right into a tapped hole on my bench fixture with zero binding, and the socket head grabbed my Allen key cleanly. Exactly what I needed for a quick jig repair.

Miles ★★★★★

Threaded perfectly into my milling vise without any binding, and the hex head gave my 4mm Allen key a nice, snug fit. Exactly what I needed for a sturdy fixture plate setup.
