HOLO-KROME 42048 براغي ضبط مقبس بنقطة كروية 3/8-16 × 1/2 بوصة | سبيكة فولاذ بأكسيد أسود حراري (100/عبوة)

These work perfectly for aligning jigs on my drill press table—the hex socket drive makes installation in tight spots a breeze. The black oxide finish looks clean and should resist rust well in my shop. Exactly what I needed for these clamping applications.

The knurled cup point really bites into the shaft—no slippage at all once torqued down. Worked perfectly for securing a collar on a motor mount.

I needed these for a jig I was building and the alloy steel with thermal black oxide finish seems really durable. The hex socket drive made tightening them into tapped holes straightforward with no rounding.
