براغي رأس أسطوانية #4-40 × 7/16" | محزز سداسي | ستانلس ستيل 18/8 (500 / عبوة)

I was worried the hex socket would strip on such small screws, but the 18/8 stainless steel is surprisingly tough and the drive engages perfectly every time. Used them to repair a jig at my workbench and they threaded cleanly without any binding.

These tiny 4-40 screws held perfectly when I used them to rebuild a small jig for my drill press. The 18/8 stainless feels solid and the hex socket made installation much easier than dealing with a slot head.

The hex socket drive on these little 18/8 stainless screws bites cleanly every time, and the 500-count pack means I’ve got plenty for all my jig-building without a second order. They’re holding up great in the precision assemblies I’ve been tweaking this week.
