Customer Reviews (4.6 / 5 · 5 reviews)

Riley ★★★★★

Needed a strong, long bolt for a jig on the mill, and these 100mm socket cap screws handled the torque perfectly without any stripping. The black oxide finish resisted chips and coolant splashes better than I expected.

Benjamin ★★★★★

The flat head design sat flush perfectly in my aluminum jig plate, and the 12.9 grade alloy steel feels incredibly tough. I torqued them down without a single strip or break.

Timothy T. ★★★★★

Used these for mounting a heavy jig plate to a workbench, and the partial threading made alignment much easier. The black oxide finish looks sleek and hasn't shown any rust after a few weeks in a humid shop.
