Value Collection 701223BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 701223BR is a button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Manufactured from alloy steel with a black oxide finish, this fastener features a 5/8-11 UNC thread and a 2-1/4 inch length under the head. The button head profile reduces snag points in assemblies, while the 3/8 inch hex socket drive allows for installation with standard Allen keys or hex bit drivers. Hardness is rated at 36-43 HRC, providing strong resistance to shear and tensile loads in demanding mechanical assemblies. Licensed tradespeople and industrial maintenance technicians are the typical installers.

This screw is suited for use in machine frames, fixtures, guards, and structural assemblies where a flush or semi-flush head profile is preferred over a standard hex head or socket head. The black oxide coating offers mild corrosion resistance and reduces light glare on exposed fasteners, making it appropriate for both indoor mechanical and light industrial environments. It conforms to ANSI/ASME B18.3 and ASTM F835 standards, ensuring dimensional and strength compliance for engineered assemblies.

Key Features

• Button head profile provides a low-profile, snag-resistant surface in assembled components
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide finish for mild corrosion resistance and reduced surface glare
• 5/8-11 UNC Class 3A thread fit for precise, tight-tolerance engagement
• 3/8 inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and material standards

Compatibility

Designed as a standard replacement or new-installation fastener for any application specifying a 5/8-11 UNC button socket cap screw per ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with fastener torque requirements for the specific assembly. Always consult the equipment manufacturer's torque specifications for 5/8-11 alloy steel fasteners before installation. Ensure mating threaded holes are clean and free of debris prior to assembly. Do not impact-drive button socket cap screws, as this can damage the hex socket drive recess.
