Andrew ★★★★★

The black oxide finish on these M4 screws looks sharp and held up fine while I torqued them into a steel fixture. Threads ran clean through the tap holes, no chips or binding, and the hex socket seated deep so the driver didn’t slip once. For 400 pieces at this grade, it’s hard to beat the value.

Lily Y. ★★★★★

Just finished a small jig for the workshop and these M4 x 30mm screws fit the hex driver perfectly. The 12.9 alloy steel feels really solid, and the 400-count package should last through several more builds. Very pleased with the quality for the price.

Violet ★★★★★

The black oxide finish on these M4-0.7 x 30mm screws holds up nicely against scratches when I’m swapping out jigs, and the hex socket drive bites cleanly every time. Class 12.9 alloy steel feels rock solid for the price, and having 400 in one box means I won’t be reordering for a while.
