Customer Reviews (4.4 / 5 · 5 reviews)

Isabella ★★★★★

1500 pieces for this price means I’ll never worry about running out mid-project, and the 18/8 stainless steel finish looks clean on my jigs. The hex socket drive seated perfectly with my Allen key, no stripping or wobble.

Andrew ★★★★★

Exactly 1500 pieces in the bag, which saved me from ordering short again—every single M3 screw I’ve used so far has threaded cleanly into my 3D printed jigs without stripping.

John ★★★★★

Bought a big pack for a jig I'm building, and every single one of these M3 countersunk bolts threaded in smoothly with no binding. The hex socket drive held the driver bit firmly without stripping, and the 18/8 stainless steel feels solid for the price.
