Value Collection 701130PR Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 701130PR is a button socket cap screw designed for applications requiring a low-profile head and high tensile strength. It features a 1/4-20 UNC thread and a length under the head of 2.5 inches, making it well suited for medium-depth fastening in metal assemblies. The screw is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces surface glare. Drive engagement is through a 5/32-inch hex socket. Hardness is rated at 36-43 HRC, conforming to ANSI/ASME B18.3 and ASTM F835 standards. Licensed machinists, millwrights, and maintenance mechanics are the typical installers.

This button socket cap screw is used in mechanical assemblies, machine guarding, jigs, fixtures, and fabricated steel structures where a flush or near-flush head profile is preferred. The black oxide coating makes it a common choice in applications where light aesthetic control or minimal light reflection is needed. It is fully threaded and right-hand drive, compatible with standard 1/4-20 tapped holes in both production and maintenance environments.

Key Features

• Button head profile provides a low-profile, rounded top surface for clearance-sensitive assemblies
• 1/4-20 UNC fully threaded, right-hand thread direction
• 5/32-inch hex socket drive for standard allen key or hex bit engagement
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or standard fastener for use in any assembly with a 1/4-20 UNC tapped hole requiring a button head cap screw per ANSI/ASME B18.3.

Installation Notes

Installation requires a 5/32-inch hex key or compatible hex socket bit. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound or torque per assembly specifications when required by the application. Always use proper personal protective equipment when working with fasteners in powered or pressurized assemblies.
