Value Collection C703332 Hex Cap Screw 9/16-12 X 6 in Grade 8

Product Description

The VALUE COLLECTION C703332 is a Grade 8 steel hex head cap screw sized 9/16-12 x 6 inches, designed for high-strength bolted connections in demanding mechanical, structural, and industrial applications. The partially threaded shank provides a bearing surface under the head, which is essential for shear-loaded joints and close-tolerance bolt patterns. Thread form follows the Unified National Coarse (UNC) standard at 9/16-12, with length measured under the head at 6 inches. The uncoated finish means no surface treatment has been applied, making these fasteners suitable for applications where coating thickness tolerance matters or where a secondary coating will be field applied. Typically installed by millwrights, ironworkers, maintenance mechanics, and general contractors.

These cap screws are suited for heavy equipment assembly, structural steel connections, machinery mounting, and fabrication work where Grade 8 tensile strength is required. The 9/16-12 UNC thread is a common size across agricultural equipment, industrial frames, and OEM machinery. Sold in a package quantity of 25, this lot is appropriate for shop stock, maintenance crib inventory, or project-specific fastener kits requiring consistent Grade 8 specification throughout.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• 9/16-12 UNC thread — standard coarse pitch for broad tooling compatibility
• Partially threaded shank provides a smooth bearing surface for shear-loaded joints
• Uncoated finish — no added coating thickness variation
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards
• Package quantity of 25 for efficient stocking and project use

Compatibility

Designed as a standard 9/16-12 UNC Grade 8 hex head cap screw per ASME B18.2.1 and SAE J429, compatible with any application specifying this thread size, length, and strength grade.

Installation Notes

Installation of Grade 8 fasteners should be performed by qualified mechanics or ironworkers familiar with proper torque procedures for the joint material and application. Always verify the mating nut or tapped hole is rated for Grade 8 loading before assembly. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards — do not substitute generic torque values. Inspect threads for damage before installation and ensure the joint surfaces are clean and free of debris.
