Value Collection 821160MSC Flange Bolt 1/2-13 Unc 1-1/2 in Grade 8

Product Description

The VALUE COLLECTION 821160MSC is a smooth flange bolt designed for structural and mechanical fastening applications where a broad bearing surface is needed without a separate washer. Sized at 1/2-13 UNC with a 1-1/2 inch length under head, the bolt is fully threaded along its entire shank. It is manufactured from Grade 8 alloy steel with a phosphate and oil finish that provides a baseline level of corrosion resistance and lubricity. The smooth flange diameter measures 1-5/64 inches (1.0781 inches). This fastener conforms to SAE J429 standards and is appropriate for use in heavy equipment, industrial machinery, and structural assemblies requiring a high-strength, unified coarse-thread fastener.

This smooth flange bolt is suited for mechanical and industrial assembly work where Grade 8 strength and a built-in bearing flange simplify installation. Typical applications include equipment frames, brackets, and mounting hardware where vibration resistance and load distribution across the flange face are required. The hex drive allows installation with standard hex wrenches or sockets. Minimum order quantity is 50 pieces; each unit is packaged individually for inventory purposes.

Key Features

• 1/2-13 UNC fully threaded shank — no unthreaded grip area
• Grade 8 alloy steel construction for high-strength fastening
• Smooth flange eliminates need for a separate flat washer
• 1-5/64 inch (1.0781 inch) flange diameter distributes clamping load
• Phosphate and oil finish provides moderate corrosion and galling resistance
• Meets SAE J429 standard for mechanical and chemical requirements

Compatibility

Designed as a standard 1/2-13 UNC smooth flange bolt suitable for general industrial, mechanical, and structural fastening applications that specify Grade 8 alloy steel and SAE J429 compliance.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 1/2-inch fastener. Always verify that the mating threaded hole or nut is also rated for Grade 8 loads before torquing. Follow applicable torque specifications from the equipment manufacturer or a recognized fastener torque standard for 1/2-13 UNC Grade 8 hardware. Inspect threads for damage or contamination before assembly.
