Value Collection 825064MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825064MSC is a serrated flange bolt designed for secure fastening in applications where standard hex bolts require additional vibration resistance. The integrated serrated flange distributes clamping load across a wider bearing surface while the teeth bite into the mating material to resist loosening under dynamic loads. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. The 1/4-20 UNC thread is fully threaded along its 1-3/4 inch length under head, making it suitable for through-bolting or engagement across the full grip range. Installers in HVAC, electrical, and light mechanical trades will recognize this as a standard corrosion-resistant fastener for panel and bracket assembly.

This bolt is suited for light to medium-duty fastening tasks in residential and commercial applications. Common uses include securing electrical enclosures, HVAC cabinet panels, sheet metal brackets, and equipment mounting hardware where vibration-resistant fastening is required without a separate lock washer. The hex drive accepts standard 7/16 inch hex tooling. This fastener is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for shop stock or job-lot procurement by trade contractors.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Fully threaded 1-3/4 inch length under head for maximum thread engagement
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish for corrosion protection in typical indoor and sheltered environments
• ASME B18.6.3 dimensional compliance ensures consistent fit with standard hex tooling
• 0.56 inch flange diameter for broad bearing surface on thin or soft substrates

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt compatible with any tapped or through-hole application specifying a 1/4-20 UNC fully threaded flange bolt to ASME B18.6.3 or SAE J429.

Installation Notes

Installation is performed by qualified tradespeople using standard 7/16 inch hex wrenches or sockets. Always de-energize electrical equipment and follow lockout/tagout procedures before replacing or installing fasteners on energized panels or assemblies. Do not exceed the torque range appropriate for Grade 5 fasteners at this thread size per applicable manufacturer or code guidance. Inspect the serrated flange face and mating surface for debris or burrs that could reduce clamping effectiveness before installation.
