1/4-28 x 5/16 Cup Point Slotted Headless Set Screw is selected when legacy equipment, blind access, or simple service tooling calls for a slotted headless set screw. The headless form keeps the fastener contained in the tapped component while the screwdriver slot remains the drive interface. The cup point uses a hollow rim for localized contact on the mating shaft or component surface.
The format suits knurled knobs, hand wheels, shaft collars, and access points where a screwdriver is easier than a key when a slotted headless set screw is already shown on the drawing or parts list. Square Head Set Screws remain a wrench-driven alternative in this catalog section.
Cold Headers supports exact-size sourcing when a drawing or parts list calls for slotted headless set screw hardware. Check the diameter, length, drive access, mating material, and whether cup-point marking is acceptable before ordering.
