براغي ضبط برأس كوب بلاستيكي مقاس 3/4-10 × 1" | فولاذ سبائكي (50/عبوة)

Finally got these set screws for a stubborn application on my mill and the nylon pellet tip seats into the workpiece without any galling, which is exactly what I needed. The hex socket drive takes a lot of torque before the alloy steel even thinks about stripping, and at 3/4-10 they fit the tap perf

The hex socket drive gripped my Allen key perfectly even in that cramped spot behind the motor mount—no stripping at all. The nylon pellet tip held firm against the shaft without marring the surface, and all 50 pieces came threaded clean with no burrs. Definitely my go-to for locking adjustments now

Installed a dozen of these in a machine stand yesterday, and the nylon pellet holds tight without marring the shaft. The hex socket gave me great leverage in that awkward spot under the frame. Exactly what I needed for a secure hold.
