براغي ضبط رأس سداسي بنقطة كوب محززة مقاس 5/8-18 × 5/8 بوصة | فولاذ سبائكي (50 / عبوة)

The knurled cup point really bites into the material on these, and the hex drive gave me plenty of torque for a tight fit. Pack of 50 is good value for the shop.

The hex socket drive made it easy to tighten these down in a cramped engine bay where a wrench wouldn't fit. Really solid alloy steel construction, no stripping or deformation after torquing them to spec.

Installing these on a stubborn sprocket was a breeze thanks to the hex socket drive, which gave me plenty of leverage in a tight spot. The alloy steel feels really sturdy, and the knurled cup point held firm without slipping.
