M6-1 x 12mm 內六角螺絲 | 平頭六角驅動 | 全螺紋 | 316不鏽鋼 (300個/包)

Had to swap out some cheap bolts on a custom jig and these 316 stainless M6s fit perfectly—the hex socket made installation a breeze with no stripped heads. They're exactly the right length for my assembly and feel noticeably tougher than the standard ones I used before.

Installed these on a marine railing after my old ones rusted, and the 316 stainless is holding up perfectly against the salt spray. The flat head sits flush without snagging, and the hex socket drive makes tightening them in tight spots a breeze.

The hex socket drive on these M6-1s seats the Allen key with zero wobble, and the 316 stainless finish feels properly tough for jig building. Full threads cut cleanly through aluminum stock. Pack of 300 is plenty for a few custom rigs.
