Value Collection 201217BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 201217BR is a button socket cap screw designed for applications requiring a low-profile fastener head with high clamping strength. Built from alloy steel with a black oxide coating, this screw offers solid corrosion resistance and a clean finished appearance. It features a 5/8-11 UNC thread at 1-1/4 inches in length under the head, driven by a 3/8-inch hex socket. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. This screw is appropriate for use by mechanical contractors, millwrights, equipment technicians, and industrial maintenance professionals.

This fastener is suited for mechanical assemblies, machine guards, fixtures, and industrial equipment where a flush or recessed button head profile is needed. The 5/8-11 UNC thread class 3A fit ensures consistent engagement with standard tapped holes. Black oxide finish makes it a practical choice in environments where mild corrosion resistance and a dark, non-reflective surface are required. Sold individually with a minimum order quantity of 10 units.
