Samuel C. ★★★★★

I needed long M3s for a tooling project and these 50mm ones with the partial thread gripped perfectly where I needed it. The hex socket drive made installation a breeze, and the zinc plating looks clean and durable.

Kevin ★★★★★

Finally got around to rebuilding a jig fixture that needed these exact specs; the 12.9 alloy steel feels incredibly solid compared to the cheaper 8.8 stuff I used before. The zinc plating on every screw looked clean and uniform right out of the bag, which saved me from having to chase them for fit.

Christopher ★★★★★

Had to order longer bolts for a tight jig setup, and these M3x50mm screws fit perfectly without any wobble. The hex socket drive made installation a breeze even in a cramped space, and the zinc plating looks uniformly applied.
