Value Collection 701203PR Button Socket Cap Screw 1/2-13 X 3

Product Description

The VALUE COLLECTION 701203PR is a button socket cap screw designed for applications requiring a low-profile head and high clamping strength. Sized at 1/2-13 UNC thread by 3 inches in length under the head, it is fully threaded and driven with a 5/16-inch hex socket. Manufactured from alloy steel with a black oxide finish, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. The button head profile reduces interference in tight clearance assemblies while maintaining a hardness rating of 36-43 HRC. It is well suited for mechanical assemblies, equipment frames, and fabricated structures where a flush or recessed fastener head is preferred.

This screw is appropriate for general industrial, manufacturing, and maintenance applications. The 1/2-13 UNC thread size and 3-inch grip length make it a practical choice for medium to heavy-duty fastening tasks in fabrication shops, machine assembly, and field service environments. A right-hand thread direction and Class 3A thread fit ensure reliable engagement with standard tapped holes and nuts.

Compatibility

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

Installation Notes

Installation is performed with a 5/16-inch hex key or socket driver. Power down and de-energize any equipment before servicing fasteners in live assemblies. Do not exceed the rated hardness class by substituting fasteners of a lower grade in high-load applications. Torque to the value specified by the assembly engineer or equipment manufacturer for the applicable joint design.
