Customer Reviews (4.6 / 5 · 5 reviews)

Zoe ★★★★★

These little screws are perfectly uniform across the whole bag of 600, which saved me a ton of time calibrating my jig setup. The hex socket drive feels crisp and the zinc plating gives them a clean, consistent look against the steel.

Chloe W. ★★★★★

Having to swap out a stripped screw on a jig this morning, I was glad these were already in my hardware drawer. The 12.9 alloy steel feels noticeably tougher than the standard hardware store stuff, and the zinc plating keeps them looking clean even after some handling.

Isabella K. ★★★★★

Used these in a jig I built for drilling small PCBs, and the 12.9 alloy steel held up perfectly under repeated clamping torque. The hex socket drive stayed clean and didn’t strip even after multiple adjustments.
