M12-1.75 X 100mm 內六角螺絲 | 六角驅動 | 全牙 | 316 不鏽鋼（每包 25 個）

The threads cut clean and started by hand without any galling, which tells me the 316 stainless is high quality. I used them to bolt down a steel fixture plate and they torqued up to spec without a hint of deformation.

Installed these on a marine-grade tooling fixture I’m building, and the 316 stainless steel feels significantly more corrosion-resistant than standard 304. The hex socket drive seated perfectly without any cam-out, and the fully threaded shaft gave me solid clamping force. Exactly the durability I n

Used these for a custom jig I was building and the fully threaded length made positioning exactly where I needed it so much easier. The hex socket drive bit snugly without any wobble, which I appreciate.
