Customer Reviews (5.0 / 5 · 5 reviews)

John ★★★★★

Packed 600 of these per order and the hex head fits a standard 7mm socket perfectly—threads are clean with no binding. Used them on a few stubborn brackets and the yellow zinc finish held up to light scuffing without flaking.

Elizabeth ★★★★★

Finally got around to replacing all the old hardware on my workbench jigs, and these M4 hex heads drive in smoothly with a socket. The Class 8.8 steel feels sturdy enough for repeated adjustments, and the yellow zinc coating gives them a nice, consistent look across all six hundred pieces.

Richard ★★★★★

Used these to fasten some brackets onto a motor mount, and the class 8.8 steel held torque without stripping. The yellow zinc coating looks clean and hasn't shown any rust after a few weeks of light exposure.
