Customer Reviews (5.0 / 5 · 5 reviews)

Stella ★★★★★

The hex socket drive grips cleanly with no stripping even after I torqued them down in a tight spot, and the black oxide finish looks sharp against the steel bracket. Used a pair as a pivot for a custom linkage and the shoulder spun true with zero slop.

Zoe ★★★★★

The precision ground shoulder on these screws holds a small gear perfectly in place, working as a bearing surface just as described. They threaded cleanly into my setup without any binding.

Timothy ★★★★★

The hex socket drive engaged perfectly with my Allen wrench, and the thermal black oxide coating looks sleek and seems tough. These made great pivot pins for a small jig I built—much tighter tolerance than the hardware store bolts I’ve used before.
