Value Collection 201220BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 201220BR is a button socket cap screw designed for applications requiring a low-profile head with high clamping strength. It features a 5/8-11 UNC thread, a 1-1/2 inch length under head, and a 3/8 inch hex socket drive. Manufactured from alloy steel with a black oxide finish, it delivers a hardness rating of 36-43 HRC and meets ANSI/ASME B18.3 and ASTM F835 standards. The fully threaded shank and Class 3A thread fit ensure consistent engagement and reliable torque transfer in demanding assemblies.

This screw is suited for mechanical, industrial, and structural assembly work where a flush or recessed fastener head is preferred over a traditional hex head. Typical applications include machine frames, fixtures, tooling plates, guards, and enclosures across manufacturing and maintenance environments. The black oxide coating provides moderate corrosion resistance and reduces light reflection, making it a common choice in fabrication shops and equipment assembly lines. Licensed mechanics and industrial maintenance technicians are the primary installers.

Key Features

• 5/8-11 UNC thread with Class 3A fit for consistent engagement and minimal slop
• 1-1/2 inch length under head, fully threaded shank
• 3/8 inch hex socket drive for standard Allen key or hex bit installation
• Alloy steel construction rated 36-43 HRC for high-strength fastening
• Black oxide finish for moderate corrosion resistance and low-glare appearance
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and performance standards

Compatibility

Designed as a standard UNC button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835, suitable for use in any application requiring a 5/8-11 threaded fastener with a button head profile and 3/8 inch hex drive.

Installation Notes

Install using a 3/8 inch hex key or hex socket bit. Ensure the mating threaded hole or nut is clean and free of debris before driving. Apply thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the rated torque capacity for the fastener grade and size per applicable industry standards.
