Value Collection 201223BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 201223BR is a button socket cap screw designed for bolted assemblies where a low-profile head is required. It is fully threaded with a 5/8-11 UNC thread and measures 2 inches in length under the head. The button head design keeps the fastener profile close to the surface, making it well suited for applications where clearance is tight. Drive engagement is through a 3/8-inch hex socket. The alloy steel construction is finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection. Hardness is rated at 36 to 43 HRC. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards and is installed by machinists, millwrights, and general maintenance technicians.

This screw is used in general industrial, mechanical, and structural bolting applications where a button head socket drive is specified. The low-profile head suits panels, guards, fixtures, and assemblies where a raised hex-head fastener would create interference or a snag hazard. The right-hand, Class 3A thread fit ensures consistent engagement with standard tapped holes. Black oxide finish makes it a common choice for machine frames, brackets, and tooling fixtures where appearance and moderate corrosion resistance matter.

Compatibility

Designed as a standard-fit replacement or new-installation fastener for any tapped 5/8-11 UNC hole requiring a button head socket cap screw per ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is performed with a 3/8-inch hex key or socket drive tool. Ensure mating tapped holes are clean and free of debris before threading. Apply thread lubricant or anti-seize as required by the assembly specification. Follow applicable mechanical codes and the equipment manufacturer's torque requirements for 5/8-inch fasteners.
