براغي مقبس سداسي بنقطة كوب مخددة 5/16-24 × 7/8 بوصة | فولاذ سبائكي (100/عبوة)

The hex drive bites perfectly into my Allen wrench, and the knurled cup point gives a firm, non-slip grip during assembly. These alloy steel screws feel solid and consistent across the whole bag.

I was a bit worried about them slipping, but the hex socket drive let me get a solid final turn in a super tight spot. The alloy steel feels really sturdy, and they threaded perfectly on the first try. Exactly what I needed for a precise adjustment.

The knurled cup point really bit into the shaft, no slippage at all once torqued down. Alloy steel feels solid, and the hex drive worked perfectly in a tight spot.
