M5-0.8 x 50mm 內六角螺絲 | 平頭內六角驅動 | 部分螺紋 | 316 不鏽鋼 (200 / 包)

I needed a precise fastener for a custom jig build, and these M5 socket cap screws threaded perfectly into place without any wobble. The 316 stainless finish gives me confidence they'll hold up in the shop environment.

Installed these in a marine jig last week and the partial threading made alignment much easier. The flat head sits perfectly flush, and the 316 stainless shows no rust after saltwater exposure.

The partially threaded shank on these M5 bolts made aligning them in my jig much easier than fully threaded ones. The hex drive seated firmly without any stripping.
