Brass Cup Point Socket Set Screws

Brass cup point socket set screws are headless threaded fasteners used to secure collars, hubs, gears, pulleys, knobs, handles, and other components to shafts or mating parts. The internal hex socket allows installation through compact openings, while the cup-shaped point creates localized rim contact against the mating surface.

Cup point geometry is commonly selected where concentrated holding contact is needed to help resist relative movement between assembled components. Depending on the mating material and installation conditions, the point may leave a witness mark or shallow indentation on the contacted surface. These fasteners are often used in electrical equipment, instrumentation, controls, enclosures, fixtures, light-duty machinery, adjustment assemblies, maintenance repairs, and replacement applications where brass is specified.

Brass provides a nonferrous material option with a distinctive appearance, general resistance to ordinary atmospheric corrosion, and useful electrical conductivity. Final product selection should reflect the actual mechanical load, environmental exposure, electrical requirements, mating material, and dimensional needs of the assembly.

Cold Headers supplies brass cup point socket set screws in a range of inch thread sizes and lengths, including uncommon and difficult-to-source configurations. Individual product pages provide exact thread size, screw length, nominal diameter, hex socket size, cup point diameter, and other verified technical information where available.

Why Use a Brass Cup Point Set Screw?

• Cup point contact: The recessed point creates rim-focused contact with the mating surface.
• Headless design: Allows installation within or below the surrounding component surface.
• Internal hex drive: Supports installation with a hex key where external wrench clearance is limited.
• Brass construction: Provides a nonferrous option for electrical, instrumentation, decorative, and general industrial assemblies.
• Exact-size selection: Product pages allow engineers and purchasers to compare thread, length, socket, and cup point dimensions.

Selecting the Correct Brass Cup Point Set Screw

Begin by confirming the required thread size and screw length. Then review the hex socket size to ensure the proper installation tool is available. Cup point diameter, mating-surface material, available access, required holding action, allowable surface marking, and whether brass is appropriate for the load and service conditions should also be considered. Cup point set screws should not be substituted automatically for flat, oval, cone, or dog point styles because each point geometry creates a different contact condition.
