M8 X 40mm 소켓 캡 나사 | 육각 소켓 드라이브 | 합금강 아연 도금 (140 / 팩)

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

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.

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.
