Value Collection 822694MSC Flange Bolt 5/16-18 Unc 1-1/4 in Grade 8

Product Description

The VALUE COLLECTION 822694MSC is a smooth flange bolt designed for high-strength fastening applications where a built-in load-distributing flange eliminates the need for a separate washer. Manufactured from Grade 8 alloy steel with a phosphate and oil finish, this bolt delivers strong corrosion resistance and reliable clamping force. The 5/16-18 UNC thread runs the full length under the head at 1-1/4 inches, and the 11/16-inch smooth flange diameter provides even load distribution across the mating surface. It is driven by a standard hex drive. Licensed tradespeople and maintenance technicians working on mechanical assemblies, HVAC equipment frames, and structural hardware connections commonly specify this fastener.

This bolt is suited for general industrial, mechanical, and equipment-mounting applications where a fully threaded, high-grade fastener is required. The smooth flange style is appropriate for installations where the bolt seats directly against a flat surface and a serrated or locking flange is not needed. Applications include equipment bases, bracket assemblies, and structural connections in commercial and light industrial environments. Sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile and proof-load strength
• Fully threaded shank — 5/16-18 UNC thread runs the full 1-1/4 inches under head
• Smooth flange at 11/16 inches diameter distributes clamping load without a separate washer
• Phosphate and oil finish provides corrosion and wear resistance
• Hex drive for standard socket or wrench installation
• Meets SAE J429 fastener standard

Compatibility

Designed as a standard 5/16-18 UNC smooth flange bolt suitable for general mechanical and equipment-fastening applications requiring a Grade 8 alloy steel fastener conforming to SAE J429.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a 5/16-18 UNC bolt head. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for Grade 8 hardware. Ensure mating threads are clean and free of debris before installation. Do not mix inch-series and metric fasteners in the same assembly.
