3/8-16 x 3/4 Cup Point Slotted Headless Set Screw gives maintenance teams a slotted headless set screw option with a cup point for general shaft and hub holding work. Because the screw has no head, it can thread below the surface of a collar, hub, knob, or housing when the tapped hole permits. The cup point is commonly used where localized holding contact is desired and the mating surface can tolerate set screw marks.

For collars, hubs, small gears, light shafts, and hardware where the set screw sits below the surface, verify the thread, length, and mating surface before substituting another set screw style. Review Knurled Point Alloy Steel Socket Set Screws when the application calls for a more aggressive vibration-grip point.

Cold Headers helps match exact sizes for legacy hardware, maintenance work, and distributor sourcing requests. When replacing a removed screw, compare thread, length, slot condition, and whether the cup point matches the original intent.
