Customer Reviews (4.6 / 5 · 5 reviews)

Eva Y. ★★★★★

The threading is clean and consistent on every single screw, which made driving them into steel beams a breeze. They feel rock-solid in hand and the plain finish is perfect for my indoor machinery build.

John ★★★★★

I needed some heavy-duty fasteners for attaching steel brackets to a frame, and the partial threads on these made it easy to get a tight fit without binding. The Grade B steel feels sturdy enough for the job, and the hex heads gave my wrench a solid grip.

Joseph Y. ★★★★★

Bought these for rebuilding a heavy gate hinge and the partially threaded design grabbed cleanly without needing to pre-tap. The steel feels substantial for the size, shipped straight and not a single one with burred threads.
