Ava G. ★★★★★

These M16 bolts held firm when I torqued them down on a heavy press fixture, the hex head gave my socket a solid bite with zero rounding. The partial threading made alignment quick on the first try, which saved me a good ten minutes of fiddling.

Edward L. ★★★★★

Used these to secure a jig fixture on our mill table and the Class 10.9 strength gave me real peace of mind under heavy vibration. The 320mm length with partial threading seated perfectly without bottoming out. Wish they came in a bigger pack, but the four pieces were machined clean and torqued down

Scarlett T. ★★★★★

These bolts are exactly the right length for my heavy equipment jig, and the hex heads let my socket wrench grip them firmly without slipping. The 10.9 steel rating gives me confidence they can handle the load I need.
