Cup Point Square Head Set Screws

Cup point square head set screws are headless threaded fasteners designed to secure collars, hubs, gears, pulleys, couplings, knobs, handles, and other shaft-mounted components. The external square head allows installation with an adjustable wrench, box wrench, or open-end wrench, while the recessed cup point creates localized rim contact with the mating surface to help secure assembled components. This traditional drive style remains widely specified for industrial equipment, maintenance applications, and legacy machinery.

Cup point geometry is commonly selected where concentrated holding contact with the mating shaft or component is desired. Depending on the mating material and installation conditions, the cup point may leave a witness mark or shallow indentation on the contacted surface. These fasteners are frequently used in power transmission equipment, agricultural machinery, pumps, conveyors, machine tools, industrial maintenance, repair operations, and OEM assemblies where a square head drive is specified.

Proper fastener selection should consider thread size, screw length, square head dimensions, wrench clearance, mating material, installation access, and acceptable surface marking. Individual product pages provide verified thread size, screw length, nominal body diameter, square head dimensions, and additional engineering information where available to assist engineers and purchasing professionals in selecting the appropriate fastener.

Cold Headers supplies cup point square head set screws in a broad range of inch thread sizes and lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.

Why Choose Cup Point Square Head Set Screws?

  • Cup point geometry: Creates localized rim contact with the mating surface.
  • Square head drive: Designed for installation using standard wrenching tools.
  • Headless threaded design: Installs with the threaded body while providing convenient wrench engagement.
  • Industrial applications: Commonly used on collars, hubs, pulleys, gears, couplings, and shaft-mounted components.
  • Verified engineering dimensions: Product pages provide thread size, screw length, square head dimensions, and other engineering data where available.

Selecting the Correct Cup Point Square Head Set Screw

Begin by confirming the required thread size and screw length. Review the square head dimensions, available wrench clearance, mating material, required holding action, and acceptable surface marking before selecting a fastener. Cup point square head set screws should not be substituted automatically for flat point, cone point, oval point, dog point, or knurled cup point designs because each point geometry provides different contact characteristics.

Cold Headers Inc. has supplied specialty industrial fasteners since 1962. Our catalog helps engineers, distributors, maintenance teams, and purchasing professionals locate exact sizes, uncommon lengths, and difficult-to-find square head set screws without unsupported inventory claims.
