Customer Reviews (4.6 / 5 · 5 reviews)

Samuel S. ★★★★★

Used a full package of these on a jig build and not a single stripped socket or seized thread. The black oxide finish held up well against coolant splashes, and the low head design gave me just enough clearance under the clamp plates.

Abigail ★★★★★

The low head profile cleared my tight spot without any filing, and the black oxide finish looks sharp against the rail. Threads cut smooth and seated flush across all 300 pieces, zero duds in the batch.

William T. ★★★★★

Used these for a jig I was building in the shop, and the low head profile gave me just enough clearance under the work surface. The black oxide finish hasn't shown any wear after a couple weeks of clamping and unclamping.
