براغي رأس أسطوانية 5/16-18 × 1-1/8" | رأس منخفض بمحرك سداسي داخلي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

I’m replacing the low-profile bolts on a jig I inherited, and these low head socket caps fit where standard ones would stick out. The black oxide finish looks clean and seems like it’ll resist rust well in my shop.

Fit perfectly into my milling fixture’s T-slots, and the low hex head gave just enough clearance for the workpiece. The black oxide finish already saved me from a few wrench slips.

I needed a handful for a jig I was building, and the hex socket drive made install super easy. The low head profile was a pleasant surprise, letting me fit them into tight spots without any clearance issues. For the price of a 100 pack, these are solid.
