Customer Reviews (4.8 / 5 · 5 reviews)

Ryan O. ★★★★★

The hex head on these M4 brass bolts grips my driver bit perfectly without stripping. I used them for a small electronics project where the unthreaded grip section gave a clean, snug fit through the mounting holes. Exactly what I needed for a polished, corrosion-resistant finish.

Ava W. ★★★★★

The partially threaded section made these bolts sit perfectly flush in my aluminum bracket without any wobble. They tightened down smoothly with a standard hex key and the brass finish looks classy against the dark metal. Exactly what I needed for a clean, precise assembly job.

Ruby N. ★★★★★

The partially threaded shank made alignment through the clearance holes effortless, and the hex heads gripped my wrench without any stripping. These brass bolts have a nice weight to them, and all 100 arrived clean and uniform.
