1/4-20 x 3/4 Cup Point Slotted Headless Set Screw fits applications where a screwdriver-driven cup point set screw is preferred over socket-key installation. The slot can be driven with common flat-blade tools, avoiding the need to identify and carry a separate key size. The hollow-rim point can bite into the mating surface, so selection should consider whether a witness mark is acceptable.

It is a practical match for fixture stops, knobs, handles, lever hardware, and small machine adjustments, with the cup point providing localized contact on the retained component. 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.
