Customer Reviews (4.4 / 5 · 5 reviews)

Sebastian D. ★★★★★

I was impressed with the partially threaded design, which made it easy to adjust tension in my jig setup without the screws slipping. The black oxide finish feels durable and resists scratching during assembly.

James X. ★★★★★

The hex socket drive made installation onto my precision assembly a breeze, and the black oxide finish seems tough enough to resist wear. I used them to secure a jig baseplate, and the 250mm length gave me just enough reach for the clamping setup.

Chloe ★★★★★

Finally, long M5s that actually hold up—the 12.9 alloy steel takes torque without stripping, and the black oxide finish looks proper on my jig. They’re partially threaded, which made lining up the clamp plates way easier than dealing with full threading.
