Value Collection 701205PR Button Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 701205PR is a button socket cap screw designed for fastening applications that require a low-profile head with high clamping strength. It features a 1/2-13 UNC thread, a 3-1/2 inch length under head, and a 5/16 inch hex socket drive. Constructed from alloy steel with a black oxide coating, it delivers corrosion resistance and a clean finished appearance. Hardness is rated at 36-43 HRC, and the thread fit is Class 3A with a right-hand direction. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards. It is fully threaded and suited for structural and mechanical assembly work across industrial and trade environments.

This screw is used in applications where a standard socket head would protrude too far or interfere with adjacent components. The button head profile is common in machinery guards, brackets, panels, and equipment housings. It is installed by machinists, millwrights, and maintenance technicians in manufacturing, HVAC equipment assembly, and general mechanical fabrication. The black oxide finish makes it a practical choice in environments where light corrosion protection and appearance consistency are priorities.

Key Features

• Low-profile button head reduces protrusion in tight clearance applications
• Alloy steel construction with 36-43 HRC hardness for reliable clamping force
• Black oxide coating provides light corrosion resistance and a uniform dark finish
• 5/16 inch hex socket drive for standard Allen key or hex bit installation
• Fully threaded 1/2-13 UNC thread at Class 3A fit for consistent engagement
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and material standards

Compatibility

Designed as a standard 1/2-13 UNC button socket cap screw for use in tapped holes or with nuts conforming to ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Install using a 5/16 inch hex key or hex socket bit. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before fastener replacement on live assemblies. Follow applicable ASME or equipment manufacturer torque guidelines for 1/2-13 fasteners in the specific joint material.
