Customer Reviews (4.6 / 5 · 5 reviews)

Leo S. ★★★★★

Installed a batch of these on a jig frame yesterday — the hex socket drive grabbed cleanly and the black oxide finish held up well against coolant spray. The partially threaded shank gave just the right grip depth for a snug fit.

Julian N. ★★★★★

Used these for securing a tooling block on a mill, and the flat head hex drive made flush mounting simple. The black oxide finish seems durable, and the 12.9 grade held up fine under heavy clamping pressure.

Victoria U. ★★★★★

Got these for a jig I’m building, and the class 12.9 alloy steel feels incredibly solid compared to standard bolts. The partially threaded design makes alignment a breeze in tight spots.
