Customer Reviews (4.8 / 5 · 5 reviews)

Aurora ★★★★★

The hex heads fit my ratchet perfectly, and the class 8.8 steel feels solid for heavy equipment. Threads are clean and ran in smoothly with no binding.

Penelope ★★★★★

These are replacing old bolts on a press jig and the Class 8.8 rating gives me confidence they'll hold up under load. The fully threaded shaft and hex head make installation a breeze with a socket.

Lucy U. ★★★★★

I needed high-strength bolts for a trailer hitch repair, and these M16s with the 8.8 rating handled the torque without stripping. The 50-count pack left me with spares for future projects.
