M12-1.75 X 140mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 316不鏽鋼 (25 / 包)

The threading on these M12 screws is clean and precise, so they seated perfectly into my jig without any binding. The 316 stainless finish feels solid and should hold up well in a damp shop environment. Exactly what I needed for a machinery repair.

Went to replace some old bolts on a marine jig and these M12-1.75 socket caps fit perfectly in the hex driver. The 316 stainless feels solid, and the partial threading made alignment a breeze.

The 316 stainless is exactly why I grabbed these for my jig fixtures—no rust worries even with coolant splashing around. Partial threads made seating depth easy to dial in, and all 25 came with clean, sharp hex sockets.
