Value Collection 822691MSC Flange Bolt 1/4-20 Unc 2in Grade 8

Product Description

The VALUE COLLECTION 822691MSC is a smooth flange bolt designed for high-strength fastening applications requiring a bearing surface that distributes load without a separate washer. Built from Grade 8 alloy steel with a phosphate and oil finish for corrosion resistance, this bolt features a 1/4-20 UNC thread form and measures 2 inches in length under the head. The partially threaded shank provides 3/4 inch of thread engagement, leaving an unthreaded grip zone for shear-loaded joints. The 9/16 inch smooth flange diameter provides a broad seating surface, making it well suited for metal-to-metal connections in mechanical and structural assemblies. Licensed tradespeople and maintenance technicians working to SAE J429 fastener standards will find this bolt meets Grade 8 mechanical requirements.

This flange bolt is used in mechanical, industrial, and light structural applications where a hex-drive, partially threaded fastener with an integrated load-spreading flange is required. Common install scenarios include equipment frames, brackets, panels, and machine housings where consistent clamp load and alignment are critical. The hex drive accommodates standard wrenches and sockets, keeping installation straightforward in tight spaces. 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 requirements per SAE J429
• Smooth flange integrates a load-spreading bearing surface, eliminating a separate flat washer
• Partially threaded shank with 3/4 inch thread length provides a grip zone for shear resistance
• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes
• Phosphate and oil finish provides baseline corrosion and wear resistance
• Hex drive compatible with standard sockets and open-end wrenches

Compatibility

Designed as an OEM-style or replacement fastener for any application requiring a 1/4-20 UNC partially threaded smooth flange bolt conforming to SAE J429 Grade 8 specifications in inch-measurement fastener systems.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with torque specifications for Grade 8 inch-series fasteners. Always verify that the tapped hole thread form and depth are compatible with 1/4-20 UNC before installation. De-energize or lock out any equipment per applicable safety procedures before replacing fasteners in mechanical assemblies. Do not reuse fasteners that show thread damage, corrosion, or deformation.
