1/4-28 x 1 1/4 Cup Point Slotted Headless Set Screw is a slotted headless set screw for field adjustments where a flat-blade screwdriver is easier to source than a matched hex key. 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 maintenance bins, repair kits, coupling collars, and non-critical retaining locations, with the cup point providing localized contact on the retained component.

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.
