Customer Reviews (4.6 / 5 · 5 reviews)

Avery ★★★★★

Used these to secure a fixture onto a milling table, and the 85mm length gave just enough grip through the thick steel plate. The hex socket drive made installation quick without stripping.

Claire ★★★★★

The partial threading is spot on for my jig builds—no more stripping threads mid-assembly. Zinc plating held up fine through a few oily sessions, and the 12.9 hardness gives me real confidence in the clamp load.

Joshua W. ★★★★★

The hex socket drive fit my hex key perfectly, and the 85mm length was exactly what I needed for a jig repair. The partially threaded design helped with alignment, and the zinc plating looks clean.
