Customer Reviews (4.4 / 5 · 5 reviews)

Zoe ★★★★★

The hex socket drive sits deep and clean—no stripped corners even after torquing them down hard on my jig. The black oxide finish has a nice uniform matte look, and the 12.9 alloy steel feels seriously solid for the price.

Emma ★★★★★

The black oxide finish on these is exactly what I wanted for a fixture build—clean, even, and they slide into tapped holes without binding. The 12.9 alloy steel gives me confidence torquing them to spec. For 200 pieces at this price, they're a solid value.

Benjamin ★★★★★

Needed a solid batch of M8 fasteners for a jig I was building, and these 12.9 alloy screws are noticeably tougher than the standard hardware store stuff. The thermal black oxide finish also gives them a nice, uniform look against the steel.
