Customer Reviews (4.6 / 5 · 5 reviews)

Eva K. ★★★★★

The threads cut cleanly into my tooling fixture without any binding, and the black oxide finish gives them a nice uniform look that resists smudging from handling. Partial threading made alignment much easier when securing the base plate, and the hex socket seated the driver perfectly every time.

Nicholas ★★★★★

The partial threading on these M20s is exactly what I needed for my jig build—the unthreaded shank aligns perfectly in the bore. Class 10.9 alloy steel feels reassuringly solid, and every one of the 25 came out of the pack clean, no burrs on the hex socket.

Elizabeth E. ★★★★★

The black oxide finish looks properly done and held up fine during installation, no chips or uneven coating. Threads engaged cleanly on both the jig and the machine base I used them for, and the hex socket drive seated perfectly every time.
