5/16-18 x 3/16 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.
Engineers and repair technicians may specify this size for plant maintenance, shop repair, instrument housings, and service records calling out slotted hardware when below-surface installation is required. Carbon steel should be kept dry and oiled; ask about stainless options when environmental exposure is part of the job. 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.
