3/4-10 x 5/8" 尼龍粒杯端止付螺絲 | 合金鋼（50 / 包）

Those alloy steel screws are solid, and the hex drive let me torque them down precisely in a cramped spot. Fits perfectly for my jig fixture, and the nylon pellet holds without marring the shaft.

The nylon pellet cup point grips the shaft way better than a standard flat tip, and the alloy steel threads cut cleanly without galling. Fifty of them in the pack is plenty for my jig fixtures, and the hex socket let me torque them down in a tight spot without rounding out.

I needed some heavy-duty set screws for a tight adjustment point on a press, and these 3/4-10 nylon pellet cup points worked perfectly. The hex socket drive made it easy to torque them down securely even in a cramped spot.
