M3-0.5 X 16mm 內六角螺絲 | 六角驅動 | 全牙 | 316不鏽鋼 (900 顆/包)

The hex socket drive on these M3 screws bites cleanly with a standard Allen key, no stripping even after torquing them down hard on a fixture. The 316 stainless finish is smooth and uniform across all 900 pieces, which makes them easy to sort and feed quickly. Just the right length for 10mm of threa

I've been through maybe 200 of these for a jig I'm building and haven't had a single stripped head or mangled thread, which says a lot for 316 stainless. The hex socket engagement is crisp and the fully threaded length gives me plenty of grip for blind holes.

I needed a large batch of M3 screws for a custom jig, and these 316 stainless ones are exactly what I was looking for. The threads are clean and consistent, and the hex socket drive fits snugly with my Allen key.
