Value Collection D39152 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION D39152 is a partially threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade hardware. The 5/8-11 UNC thread profile and 2-3/4 inch length under head make it well suited for heavy-load bolted connections where clamping force and fatigue resistance are critical. Compliance with ASME B18.2.1 ensures dimensional consistency across production and replacement applications.

This cap screw is used in heavy equipment assembly, industrial machinery, structural steel connections, and general mechanical fabrication where Grade 8 strength requirements apply. The partially threaded shank provides a bearing surface that resists shear loads at the joint interface, making it appropriate for bolted connections subject to lateral forces. Maintenance technicians, millwrights, and fabricators working on agricultural equipment, construction machinery, or manufacturing fixtures will find this fastener meets standard torque and load specifications for 5/8-inch Grade 8 hardware.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion resistance and identification as a high-grade fastener
• Partially threaded shank resists shear loads at the joint interface
• 5/8-11 UNC thread for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and finish

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts, heavy hex nuts, and tapped holes conforming to inch-series thread standards. Suitable as a direct replacement in any application specifying a 5/8-11 x 2-3/4 inch Grade 8 partially threaded hex head cap screw per ASME B18.2.1.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel familiar with proper fastener torque procedures for Grade 8 hardware. Always de-energize and lock out equipment before servicing bolted assemblies. Use a calibrated torque wrench and apply the appropriate torque value specified by the equipment manufacturer or applicable engineering standard for 5/8-11 Grade 8 fasteners. Inspect threads and mating surfaces for damage or contamination before installation.
