براغي مقبس من النايلون بنقطة كوب #1-8 × 1-1/2 بوصة | فولاذ سبائكي (25 / عبوة)

Installed these into a small indexing fixture and the nylon pellet held firm without damaging the aluminum threads. The hex socket drive made tightening in a tight corner much easier than a slotted screw ever could.

Finally found a screw where the hex socket actually holds up under high torque without stripping. Worked perfectly for a tight adjustment inside a machinery panel where space was limited.

I needed a screw that would stay put in a tight machinery adjustment, and these hex socket drives let me apply real torque without stripping. The cup point tip seated perfectly into the nylon pellet, and the alloy steel feels solid.
