Customer Reviews (5.0 / 5 · 5 reviews)

Jason ★★★★★

The hex head grabbed my socket wrench perfectly, and the zinc plating looks clean and even across all 25 screws. They threaded into the machinery frame without any binding, which is exactly what I needed.

Carter ★★★★★

Needed these to bolt down some heavy machinery in the workshop, and the Class 8.8 steel feels solid—no flex or rounding under full torque. The zinc plating on all 25 screws was even and clean, which helps for outdoor gear too.

Natalie ★★★★★

I was a bit worried about the thread pitch matching my equipment, but the M20-2.5 cut smoothly into the steel bracket without any binding. The hex head gave my socket wrench a solid, wobble-free grip. These fully threaded bolts feel strong and hold firm under heavy torque.
