M5-0.8 X 30mm 六角穴付きキャップスクリュー | ボタンヘッド六角穴 | 全ねじ | 316ステンレス鋼 (200/パック)

Used a handful of these to secure a jig in my workshop, and the fully threaded body gripped perfectly the whole depth. The hex socket drive made them easy to tighten without stripping, and they've held up well without any rust. Exactly what I needed for long-lasting reliability.

Finally, a 316 stainless screw that actually doesn’t rust in my marine jig setup—these button heads are perfectly formed and the hex drive bites well. Used a dozen on a saltwater camera mount and they’re holding up great so far.

I’ve been swapping out cheaper screws on my jigs and these 316 stainless ones don’t show a single speck of rust after weeks in a damp shop. The fully threaded 30mm length bites cleanly, and the hex socket held up through a dozen tightenings without stripping.
