Value Collection 822687MSC Flange Bolt 1/4-20 Unc 1 in Grade 8

Product Description

The VALUE COLLECTION 822687MSC is a smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 1/4-20 UNC fully threaded shank with 1 inch of thread length under the head, providing consistent clamping force along the entire fastener length. The integrated smooth flange distributes load across a wider bearing surface, reducing the need for a separate washer. Finished with a phosphate and oil coating for corrosion resistance, this bolt meets SAE J429 Grade 8 alloy steel standards and is suited for high-stress bolted joints where tensile strength and fatigue resistance are critical.

This bolt is used in mechanical equipment assembly, automotive and powertrain components, hydraulic system mounting, and general industrial fabrication where Grade 8 tensile performance is required. The hex drive is compatible with standard socket and wrench tooling. The smooth flange face is appropriate for applications where a clean seating surface is required and marring of the mating part must be minimized. Installers working in HVAC equipment frames, compressor mounts, and electrical enclosure hardware will find this a direct-fit fastener for standard 1/4-20 tapped holes.

Key Features

• Grade 8 alloy steel construction rated to SAE J429 for high tensile and proof load strength
• Fully threaded shank allows engagement along the entire 1 inch length under head
• 9/16 inch smooth flange diameter provides integral load-spreading bearing surface
• Phosphate and oil finish delivers baseline corrosion and galling resistance
• Hex drive compatible with standard 3/8 inch drive sockets and combination wrenches
• 1/4-20 UNC thread standard ensures broad compatibility with inch-standard tapped components

Compatibility

Designed as a standard replacement or stock fastener for any assembly requiring a 1/4-20 UNC, 1 inch length under head, fully threaded smooth flange bolt conforming to SAE J429 Grade 8 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with inch-standard fastener torque procedures for Grade 8 hardware. De-energize and depressurize the assembly before servicing any bolted joint. Use a calibrated torque wrench and follow the applicable equipment manufacturer torque specification for 1/4-20 Grade 8 fasteners. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation.
