براغي رأس مقبس مقاس 1-8 × 2-1/4 بوصة | محرك مقبس سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (10 / عبوة)

Installed these on a marine railing that gets constant salt spray, and the 316 stainless is holding up perfectly without a hint of rust. The hex socket drive made tightening them into tight corners much easier than a standard hex head.

The hex socket drive is machined cleanly, so my Allen wrench seated perfectly without any wobble—these 316 stainless screws threaded into my jig like a dream. For the price per package, the finish on these is noticeably better than the cheaper ones I've used before.

Finally got around to swapping out the old bolts on my jig, and these hex socket screws were a perfect fit. The 316 stainless steel feels noticeably more solid than the standard ones I've used before.
