Customer Reviews (4.4 / 5 · 5 reviews)

Joseph D. ★★★★★

I've been using these M4 x 40mm socket set screws for a small furniture assembly, and the hex drive handles high-torque tightening without stripping. The alloy steel feels sturdy, and the flat point really helps in tight corners. No complaints so far for the price.

Miles ★★★★★

I needed a full pack of these for a jig I'm building, and the flat point grabbed perfectly without marring the shaft. They threaded cleanly into all the pre-tapped holes, exactly as you'd hope.

Evelyn S. ★★★★☆

The hex drive bit fits snugly, which is a big plus when you're working in a cramped spot. I did find a couple with slightly burred threads in the pack, but overall the steel feels solid and they work great for securing my tooling plates.
