Alloy Steel Cup Point Socket Set Screws

Alloy steel cup point socket set screws are headless threaded fasteners designed to secure gears, pulleys, collars, hubs, 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 concentrated rim contact against the mating surface.

Cup point geometry is commonly selected when localized holding contact is needed to help resist movement between assembled components. Depending on the mating material and installation conditions, the point may create a witness mark or indentation on the contacted surface. These fasteners are frequently used in machinery, tooling, automation equipment, conveyor systems, packaging equipment, adjustment mechanisms, fixtures, maintenance repairs, and replacement assemblies.

Cold Headers supplies alloy steel cup point socket set screws in a broad 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. Review the listed dimensions along with the mating material, drive access, shaft condition, required holding action, and whether surface marking is acceptable.

Why Use a Cup Point Socket Set Screw?

  • Cup point contact: The recessed point creates rim-focused contact with the mating surface.
  • Headless design: Allows the fastener to install within or below the surrounding component surface.
  • Internal hex drive: Supports installation with a hex key where external wrench clearance is unavailable.
  • Component retention: Commonly used with shafts, collars, hubs, pulleys, gears, knobs, and adjustment assemblies.
  • Exact-size selection: Product pages allow engineers and purchasers to compare thread, length, socket, and cup point dimensions.

Selecting the Correct Cup Point Set Screw

Begin by confirming the required thread size and screw length. Then review the hex socket size to ensure the correct installation tool is available. Cup point diameter, mating-surface material, available access, and the allowable level of surface marking 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.

Cold Headers Inc. has supplied specialty industrial socket fasteners since 1962. Our catalog is organized to help engineers, distributors, maintenance teams, and purchasing professionals locate exact sizes, uncommon lengths, and hard-to-find socket set screws without unsupported inventory claims.

Description N/A

0-80 x 1/16 Alloy Steel Cup Point Socket Set Screw is an Alloy Steel Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.

It is commonly used in shaft collars, hubs, and machine controls, where a headless fastener must hold a component without external head clearance. The internal hex drive allows socket-wrench access from the top of the threaded hole, which is useful when the surrounding assembly leaves little room for external wrenching.

Review the 0-80 thread, 1/16 in. length, hex socket size, and cup point diameter against the mating part before specifying the item. Always confirm that the cup point contact is acceptable for the mating component and service conditions. The cup point creates rim-focused contact that can help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for socket set screws, including short runs, uncommon lengths, and replacement requirements.

Designed for compact set-screw fastening, 0-80 x 3/32 Alloy Steel Cup Point Socket Set Screw combines Alloy Steel construction with a cup-shaped point for localized contact at the mating surface.

Typical use cases include gears, pulleys, and sprockets, especially where point contact helps position a component on a shaft. The internal hex drive keeps installation access compact while the headless body remains contained within the mating part.

For purchasing and replacement work, confirm the 0-80 thread, 3/32 in. length, socket size, and cup point diameter match the drawing or installed part. Always confirm that the cup point contact is acceptable for the mating component and service conditions. The recessed end form is often chosen where a witness mark or indentation on the mating surface is acceptable for the holding method. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify difficult set screw configurations.

For assemblies that call for an exact set screw size, 0-80 x 1/8 Alloy Steel Cup Point Socket Set Screw provides an Alloy Steel cup point design with internal hex drive access.

In couplings, knobs, and handles, this screw is often selected where the installed screw must sit inside the tapped part. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.

Selection should account for the mating material, available drive access, and whether localized point contact is acceptable. This 0-80 x 1/8 size gives buyers a precise callout for ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. Compared with a plain threaded plug, the cup-shaped end gives the installer a defined point style for holding or adjustment work. Cold Headers works with distributors, maintenance teams, and production buyers that need clear size identification for specialty socket products.

Technical Highlights

0-80 x 5/32 Alloy Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.

Applications often include tooling, fixtures, and adjustment assemblies, where compact internal-hex access matters during setup. The internal hex recess gives the installer controlled drive engagement while keeping the fastener profile inside the tapped component.

The verified dimensions below help engineering and purchasing teams compare the screw to the application before ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. The point geometry is intended for applications where localized contact is part of the retaining method, not for assemblies that require a nonmarking tip. Cold Headers helps match set screw thread, length, point style, and socket drive details for industrial purchasing and repair work.

When a drawing or maintenance bill calls for a cup point set screw, 0-80 x 3/16 Alloy Steel Cup Point Socket Set Screw identifies the required Alloy Steel thread and length clearly for purchasing.

It is commonly used in conveyors, packaging machinery, and automation equipment, where maintenance teams need repeatable socket-drive installation. The internal hex drive allows socket-wrench access from the top of the threaded hole, which is useful when the surrounding assembly leaves little room for external wrenching.

Review the 0-80 thread, 3/16 in. length, hex socket size, and cup point diameter against the mating part before specifying the item. Always confirm that the cup point contact is acceptable for the mating component and service conditions. Buyers should review the shaft or component surface condition, drive access, and required holding action before selecting this point style. Cold Headers is a useful source when the part number, thread, point style, or length is difficult to locate through standard catalog channels.
