براغي ضبط برأس مقبس بنقطة كوب من النايلون 1/4-20 × 5/8 بوصة | فولاذ سبائكي (100/عبوة)

I used these to replace some stripped screws in a jig I built, and the hex drive let me really crank them down without stripping anything. The nylon cup point sits flush and protects the surface, which is exactly what I needed.

Needed a reliable way to secure a nylon bushing in a tight corner, and the cup point on these set screws really digs in without slipping. Installed a few with a hex key and they held firm under moderate torque—solid purchase for the price.

Exactly what I needed for a tight-access adjustment on my mill's vise stop. The hex socket drive let me torque them down securely with a ball-end driver, and the nylon pellet tip keeps from marring the hardened jaw surface.
