Andrew ★★★★★

I’ve been using these M4 screws for a few weeks now, and the hex socket drive makes them a breeze to tighten even in awkward spots. The stainless steel feels sturdy and hasn’t shown any rust yet—exactly what I needed for outdoor hardware.

Robert U. ★★★★★

The cup point on these really bites into the shaft; I've had zero slippage on a few motor couplings I just assembled. Every single screw in the bag was cleanly threaded and the hex socket drove perfectly.

Harper ★★★★☆

The cup point on these M4 screws really grips the shaft well—no slipping under moderate pressure. I used a full pack for a jig build and only found two with slightly rough threads, but that’s acceptable for the price.
