Customer Reviews (4.8 / 5 · 5 reviews)

Elizabeth O. ★★★★★

Took a chance on these for a custom jig I’m building, and the 316 stainless finish is noticeably smoother than the cheaper 304s I’ve used before. The hex socket grabbed cleanly with no stripping even at torque. Glad I grabbed the 200-pack, they’ll last me through several projects.

Carter U. ★★★★★

Used a full pack on a marine railing repair and every single one seated perfectly without stripping. The 316 stainless feels solid, and the button head profile sits flush against the bracket. Exactly what I needed for outdoor hardware.

Avery D. ★★★★★

The hex drive is nice and deep, so my Allen key didn’t slip once while installing these into a custom bracket. Threads cut cleanly through 304 steel on the fixture too, no chips or galling at all.
