1/4-20 x 1-5/8" 內六角螺絲 | 鈕扣頭內六角 | 18/8 不鏽鋼 (100 / 包)

Used these to secure a jig on my drill press table, and the 18/8 stainless steel gives me confidence they won't rust even if coolant splashes on them. The hex drive bit seated perfectly every time without stripping.

The button head sits flush and clean on my jig fixtures, and the hex socket drive grips the Allen key without any slipping. I’ve torqued these down hard on a few tooling builds and not a single one has stripped or corroded after a week of use.

Used a bunch of these to assemble my workbench jig, and the button head sits flush without snagging anything. The hex drive made them super easy to install even in tight spots.
