M5 x 12mm 內六角螺絲 | 平頭內六角驅動 | 18/8 不鏽鋼 (1000個/包)

The hex socket drive grips my driver bit perfectly without any wobble, which is a huge plus for repetitive assembly work. I've already used about 200 of these on a jig project, and not a single one has stripped or shown any corrosion.

Finally, a hardware pack where every single screw has clean threads and a properly formed hex socket—no duds in the thousand. The flat head sits perfectly flush in my aluminum tooling plates, and the 18/8 stainless gives me confidence against corrosion in the shop.

Installed a set of these on a custom jig I’m building, and the hex socket drive made tightening them in tight spaces much easier than I expected. The 18/8 stainless steel finish looks clean and seems like it will hold up well in the shop.
