Customer Reviews (4.4 / 5 · 5 reviews)

Chloe R. ★★★★★

The hex socket drive made installing these into a tight jig fixture so much easier than using a regular slotted screw. I'm halfway through the thousand-pack and every one has seated perfectly without stripping.

Carter ★★★★★

Had a jig that kept coming loose with Phillips heads, these flat head socket screws solved it completely. The 18/8 stainless finish is clean and the hex drive grips tight without stripping. A full box of 1000 means I won't need to reorder for years.

Elizabeth ★★★★★

Used these for a jig I was building, and the flat head sits perfectly flush. The 18/8 stainless seems solid, and having a thousand in the pack means I won’t run out anytime soon.
