M16-2 X 60mm 圓柱頭螺絲 | 平頭六角驅動 | 全螺紋 | 316 不鏽鋼 (50 入/包)

Installing these in a marine-grade assembly was a breeze because the hex socket drive holds the bit perfectly without camming out. The fully threaded length gives a solid grip even in thicker materials, and the 316 stainless feels noticeably tougher than the regular steel ones I've used before.

Used these to build a custom jig for a machining project, and the 316 stainless took the torque without any stripping. The hex socket drive seated perfectly with my Allen key, making installation quick. Exactly the rugged, precise hardware I needed for the job.

Installed these on a saltwater dock gate last month—the flat head design sits flush perfectly. The 316 stainless is holding up beautifully against the spray with zero corrosion so far.
