براغي مقبس كوب نقطة مخدد #4-48 × 3/8 بوصة | فولاذ سبائكي (100 / عبوة)

The hex socket drive made tightening these in a cramped bracket a breeze, and the alloy steel feels solid enough to trust. The knurled cup point held its grip without stripping, even at high torque.

The knurled cup point grips really well on my shaft without marring it, and the hex drive makes adjustments in tight spots a breeze. Worked perfectly for securing a small gear on my milling machine.

Fiddly little things, but the hex socket drive made seating them in tight spots way easier than I expected. The knurled cup point grips the shaft firmly once torqued down, and all 100 arrived clean and threaded properly.
