Value Collection 701225BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 701225BR is a button socket cap screw designed for bolted assemblies that require a low-profile head and high clamping strength. It features a 5/8-11 UNC thread, a 2-1/2 inch length under head, and a fully threaded shank. The alloy steel construction delivers a hardness of 36-43 HRC, making it suitable for high-stress mechanical and structural applications. A black oxide finish provides mild corrosion resistance and a consistent dark appearance. The 3/8-inch hex socket drive accepts standard Allen keys and hex bit drivers.

This fastener is used in machinery, tooling fixtures, fabrication assemblies, and general industrial applications where a standard hex bolt head would protrude too far or interfere with adjacent components. The button head profile distributes load over a wider bearing surface than a flat head, which is useful in softer base materials or applications with close clearance requirements. Installation is typically performed by mechanical technicians, millwrights, or fabricators working to ASME or ASTM fastener specifications.

Key Features

• 5/8-11 UNC fully threaded, 2-1/2 inch length under head
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide finish for mild corrosion resistance and reduced light reflection
• 3/8-inch hex socket drive for standard Allen key or hex bit installation
• Right-hand thread, Class 3A fit for precise thread engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC fastener suitable for use in tapped holes or with mating nuts conforming to 5/8-11 UNC thread specifications per ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Shut down and de-energize any machinery before fastener replacement or assembly. Use a calibrated 3/8-inch hex key or hex socket bit; avoid worn or undersized drivers that can round the socket. Do not exceed the rated hardness tolerance of the mating tapped hole material. Follow applicable torque specifications per ASME or equipment manufacturer guidelines for 5/8-11 grade alloy fasteners.
