Value Collection 207823B Hex Head Cap Screw 5/16-18 X 5/8 in

Product Description

The VALUE COLLECTION 207823B is a 5/16-18 hex head cap screw with a 5/8-inch length under head, manufactured from 18-8 stainless steel. It features a standard UNC thread form and a 1/2-inch hex drive. The 18-8 stainless steel construction provides solid corrosion resistance in a wide range of service environments, making it a practical fastener choice for mechanical assemblies, equipment mounting, and structural connections across trades including HVAC, plumbing, and electrical work. Licensed tradespeople and maintenance technicians install these fasteners as part of standard hardware builds and repairs.

This cap screw is suited for general-purpose inch-system fastening applications where a corrosion-resistant fastener is required. The 5/16-18 UNC thread is one of the most common coarse-thread sizes in trade use, fitting standard tapped holes found in equipment panels, frames, and brackets across residential and light commercial installations. Sold individually with a minimum order quantity of 100 pieces, making it appropriate for shop stock, service vans, or project-specific bulk procurement.

Installation Notes

Installation requires a standard 1/2-inch wrench or socket. De-energize and isolate any equipment before fastening components near electrical or pressurized systems. Apply appropriate thread-locking compound or anti-seize as required by the application and manufacturer guidelines. Follow applicable codes, including NEC, IPC, or IFGC, when fastening trade equipment enclosures or structural supports.
