Customer Reviews (4.4 / 5 · 5 reviews)

Eli G. ★★★★★

I use these in jigs on my CNC router and the black oxide finish has held up well without any rust after a few months of use. The hex socket drive gives a solid bite with no cam-out.

Claire P. ★★★★★

I needed some high-strength bolts for a jig I’m building, and the 12.9 alloy steel on these feels incredibly rigid—much tougher than the usual hardware store stuff. The nylon patch is a nice touch, holding them snug without needing thread locker.

Thomas ★★★★☆

The nylon patch is a real timesaver—these stay put under vibration without needing threadlocker. The black oxide finish looks consistent across all 300, and the hex sockets were clean, no stripped heads so far. Only gripe is the lack of a tray, but for the price per piece they're a solid buy.
