10-24 x 5/16 Cup Point Slotted Headless Set Screw provides a cup point and straight slot drive for service work where a flat-blade screwdriver is the practical tool. The straight slot is useful in service kits, older equipment, and awkward access points where a screwdriver reaches more naturally than a key. Standard cup proportions run roughly 0.55 to 0.62 of nominal thread diameter, which is why the exact thread size matters.
For collars, hubs, small gears, light shafts, and hardware where the set screw sits below the surface, verify the thread, length, and mating surface before substituting another set screw style. 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.
