5/16-24 X 7/8" 內六角螺絲 | 平頭內六角驅動 | 18/8 不鏽鋼 (100 / 包)

Used these to repair a jig on my milling machine, and the hex socket drive made installation much easier than a standard slot. The 18/8 stainless feels solid and the threads cut cleanly into the tapped hole.

I replaced a few worn-out bolts on my milling jig with these, and the flat head sits flush just like I needed. The 18/8 stainless seems solid and should hold up well to cutting fluid.

The hex socket drive seated perfectly on my Allen key, and the 18/8 stainless finish feels solid for the machine guard I’m working on. Threads ran clean into the tapped holes without any binding across all 100 pieces.
