Thomas A. ★★★★★

Finally a pack of socket cap screws where every thread is clean and consistent. I was building a small jig for my drill press and these M8 x 40mm bolts cinched down perfectly with no binding. The zinc coating is even and smooth, which makes them feel higher quality than the loose bins at the hardwar

Jacob ★★★★★

These M8 x 40mm socket cap screws were exactly what I needed for rebuilding a jig. The hex socket drive made installation really quick and the zinc plating gives them a clean, solid finish that seems durable. No stripped heads or loose threads—they held tight right out of the package.

Daniel C. ★★★★☆

The zinc plating on these screws seems durable so far, which is great for metal jigs I'm working on. Only issue is a few of the socket heads came with slightly loose debris inside, but cleaning them out was quick.
