18-8 Stainless Steel Cup Point Socket Set Screws

18-8 stainless steel cup point socket set screws are headless threaded fasteners used 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 automation equipment, conveyor systems, packaging machinery, instrumentation, fixtures, adjustment mechanisms, maintenance repairs, and replacement assemblies.

The 18-8 stainless steel material provides general corrosion resistance for many industrial environments involving ordinary moisture, humidity, or routine cleaning. It is commonly considered for machinery, equipment panels, controls, and maintenance applications where stainless construction is preferred. Final material selection should reflect the actual mechanical and environmental requirements of the assembly.

Cold Headers supplies 18-8 stainless steel 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 an 18-8 Stainless Cup Point 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.
  • General corrosion resistance: 18-8 stainless steel is suitable for many industrial applications involving ordinary moisture exposure.
  • Component retention: Commonly used with shafts, collars, hubs, pulleys, gears, knobs, and adjustment assemblies.

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, required holding action, environmental exposure, and whether surface marking is acceptable 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 stainless socket set screws without unsupported inventory claims.

Description N/A

0-80 x 1/16 18-8 Stainless Steel Cup Point Socket Set Screw is an 18-8 Stainless 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 control components, where a headless fastener secures a part without external head clearance. The internal hex drive allows socket-wrench access from the top of the threaded hole, which is useful when surrounding components leave little room for external wrenching.

Review the 0-80 thread, 1/16 in. length, hex socket size, cup point diameter, and mating surface before specifying the item. Confirm that point contact, material, and service conditions fit the application. 18-8 stainless is selected for general corrosion resistance, clean appearance, and ordinary moisture exposure. The cup point creates rim-focused contact that may help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for stainless socket set screws, including uncommon lengths and replacement requirements.

Designed for compact set-screw fastening, 0-80 x 3/32 18-8 Stainless Steel Cup Point Socket Set Screw combines 18-8 stainless steel construction with a cup-shaped point for localized contact at the mating surface.

Typical use cases include gears, pulleys, and sprockets, especially where localized 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. Confirm that point contact, material, and service conditions fit the application. Use it where the assembly calls for a general-purpose stainless set screw rather than carbon or specialty material. 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 stainless set screw configurations.

For assemblies that call for a stainless set screw by exact size, 0-80 x 1/8 18-8 Stainless Steel Cup Point Socket Set Screw identifies the required 18-8 material, cup point geometry, thread, and length.

In couplings, knobs, and handles, this screw is often selected where the screw must sit inside a 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, environmental exposure, and whether localized point contact is acceptable. This 0-80 x 1/8 size gives buyers a precise callout for ordering. It fits many indoor industrial, outdoor general-service, instrumentation, and routine-cleaning applications. The point geometry gives the installer a defined end form for localized holding contact rather than a general-purpose threaded plug. Cold Headers works with distributors, maintenance teams, and production buyers that need clear size identification for specialty socket products.

0-80 x 5/32 18-8 Stainless 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 is useful 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. Confirm that point contact, material, and service conditions fit the application. Final material choice should reflect load, environment, mating material, and maintenance needs. This point style 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, material, and socket drive details for industrial purchasing and repair work.
