Customer Reviews (4.8 / 5 · 5 reviews)

Madison R. ★★★★★

The hex head on these screws gave my socket wrench a solid grip, and the 140mm length was exactly what I needed for a stubborn machinery bracket. Even with the heavy torque, the zinc plating hasn't chipped or shown any rust.

Jason Z. ★★★★★

For the price of a good dinner, these M30 bolts gave me a solid, snug fit on a heavy press frame—the partially threaded section held alignment perfectly. Zinc plating looks uniform and hasn't chipped after a week of wrenching. Only wish the bag had a few extras, but they're exactly as spec'd.

Isabella A. ★★★★★

Threads are cut clean and the zinc finish looks uniform across all twenty bolts - I could torque them down without any galling concerns. The partial thread length is exactly what I needed for sandwiching thick flanges.
