8-32 x 3/8 Cup Point Slotted Headless Set Screw is a carbon steel slotted headless set screw for adjustments that need simple drive access and below-surface installation. 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.
Typical uses include pulleys and collars on light shafting, replacement knobs, and serviceable handles, where the exact diameter and length help match a tapped hole or service record. A straight slot transmits less seating torque than a hex socket; when maximum tightening torque governs, compare alloy steel socket cup point set screws.
Use Cold Headers for specialty fastener support when maintenance records call for uncommon cup point slotted sizes. Review the tapped-hole depth, screwdriver clearance, and point contact requirements before replacing a different point style.
