M16-2 X 110mm 內六角圓柱頭螺絲 | 六角凹槽驅動 | 全螺紋 | 316不鏽鋼 (25件/包)

Installed these on a custom jig and the 316 stainless is holding up perfectly in a slightly damp environment. The full threading gave a solid, consistent grab all the way in.

The hex socket drive seats perfectly on my Allen key, zero slippage even under heavy torque. Threads ran smooth all the way through the tapped hole on my jig, and the 316 finish cleaned up easy after machining.

I’ve been using these M16 socket cap screws for mounting jigs, and the 316 stainless steel gives me confidence they won’t corrode in my workshop. The hex socket drive made them easy to tighten precisely with the right tool.
