3/4-10 × 1-1/2" براغي مقبس نقطة كوب من النايلون | فولاذ سبائك (50 / عبوة)

Got these to replace some worn out bolts on a heavy press, and the hex socket drive made seating them in a cramped spot way easier than I expected. The nylon patch holds firm enough that I didn't bother with threadlocker on the first few, and they've stayed put through a week of constant vibration.

The cup point bites into the shaft really well, and the nylon patch keeps them from backing out even with vibration. I used these on a heavy-duty jig and the alloy steel held up through a full day of torque.

Needed a set screw that could handle some serious vibration on a heavy-duty jig, and the nylon patch on these really locks in place without backing off. The hex socket drive made installation a breeze even in a tight spot.
