3/8-16 x 1 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.
Maintenance teams often review this type for appliance controls, small couplings, fixture plates, and maintenance applications that favor common tools, where a screwdriver-accessible fastener keeps service simple. Carbon steel should be kept dry and oiled; ask about stainless options when environmental exposure is part of the job. 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.
