براغي رأس مقبس M20-2.5 × 40 مم | رأس مسطح محرك مقبس سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (10/عبوة)

The hex drive on these 316 stainless screws grabbed my driver bit perfectly without any cam-out trouble. They're holding up great in a salty outdoor machinery application where regular steel would have rusted by now.

I used these for a jig I’m building, and the hex socket drive made for a much cleaner installation than standard bolts. The 316 stainless feels solid and should hold up well in my workshop.

Finally found bolts that won't rust in my saltwater setup—these 316 stainless ones are a solid upgrade. The flat head sits flush against the aluminum frame, and the threads are clean and uniform right out of the pack. Really happy with the quality for the price.
