Customer Reviews (4.4 / 5 · 5 reviews)

Lucy ★★★★★

I’ve been using these for precision fixturing on a small milling machine, and the flat head sit flush like I’d hoped. The hex drive engaged perfectly with my Allen key without slipping. Good value for a bulk pack of stainless steel.

Robert R. ★★★★★

Needed a bunch for a jig I was building, and these 20mm stainless screws fit perfectly without any binding. The flat head sits flush and the hex socket grabs cleanly every time.

Riley ★★★★★

The hex socket drive on these M6-1 screws made installation into my jig so much easier than slotted heads. For a 400-count pack of 18/8 stainless, the price is hard to beat—they're solid and the threading is clean on every single one.
