Customer Reviews (4.8 / 5 · 5 reviews)

Carter ★★★★★

Used these to secure a heavy press at work, and the 280mm length was perfect for getting through the flanges. The zinc plating seems solid so far, no rust after a couple of weeks in a damp shop.

Amelia H. ★★★★★

The hex head grabbed my 24mm socket without any wobble, and the zinc coating looks clean and uniform across all five. Threads ran smooth into my equipment frame, though I did have to chase the holes first.

Robert ★★★★★

The partially threaded section grabbed just enough for a solid hold, and the zinc coating looks uniform across all five. Wrenched them down with a socket without any stripping or binding.
