Value Collection D39163 Hex Head Cap Screw 5/8-11 X 7 in

Product Description

The VALUE COLLECTION D39163 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread size and a 7-inch length under head, manufactured from Grade 8 steel for superior tensile strength and load-bearing capacity. The zinc yellow dichromate finish provides corrosion resistance in moderate-exposure environments. This fastener meets ASME B18.2.1 and SAE J429 standards, making it a reliable choice for engineers, millwrights, and maintenance professionals working on demanding mechanical systems.

This cap screw is suited for heavy-duty bolted connections in manufacturing equipment, structural steel assemblies, machinery mounts, and similar applications where Grade 8 strength is specified. The partial thread configuration is standard practice for clamping applications where the shank must pass through a clearance hole before engaging a tapped bore or nut. Sold individually, with a minimum order quantity of 10 units.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 5/8-11 UNC thread for broad compatibility with standard inch-series hardware
• 7-inch length under head suits deep-reach or multi-layer clamping applications
• Partially threaded shank optimizes clamping force in through-bolt configurations
• Zinc yellow dichromate finish provides moderate corrosion resistance
• Conforms to ASME B18.2.1 and SAE J429 standards

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 5/8-11 UNC tapped holes, nuts, and threaded inserts used in general industrial and structural fastening applications.

Installation Notes

Installation is performed by millwrights, maintenance technicians, or mechanical assemblers using standard hex wrenches or impact tooling sized for 5/8-inch hex fasteners. Verify hole clearance and thread engagement depth before installation. Apply thread lubricant or thread-locking compound per the equipment manufacturer's specifications when required. Follow applicable torque specifications from the engineering drawings or relevant standards for Grade 8 fasteners at this thread size.
