1/4-20 x 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.

This size is relevant for appliance repair, instrument repair, fan hubs, and adjustment points on compact equipment, especially when the slotted drive is already part of the equipment design. For stainless material requirements, review Cup Point 18-8 Stainless Socket Set Screws.

For odd lengths or older slotted hardware callouts, Cold Headers can help identify the closest catalog path. The dimensional reference is ASME B18.6.2, cited here only as the slotted headless set screw dimensional standard.
