Value Collection 825058MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825058MSC is a serrated flange bolt designed for general industrial and mechanical fastening applications. It features a 1/4-20 UNC thread form with a 7/8-inch length under head and is fully threaded from tip to flange. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Made from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. Installers and maintenance technicians working with light structural assemblies, brackets, and enclosures will find this a direct off-the-shelf fastener solution.

This bolt is suited for use in residential and light commercial mechanical assemblies where vibration resistance is needed without a separate lock washer. Typical applications include HVAC equipment panels, electrical enclosures, bracket mounts, and general equipment assembly where a 1/4-20 UNC threaded connection is specified. The hex drive head is compatible with standard hex keys, nut drivers, and socket wrenches. The zinc-plated finish provides moderate corrosion resistance for indoor or sheltered installations.

Key Features

• Serrated flange integrates a locking surface that resists vibration-induced loosening without a separate washer
• Fully threaded 7/8-inch shank provides maximum thread engagement in thin or shallow assemblies
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish offers corrosion resistance for indoor and sheltered environments
• Hex drive head accepts standard socket, nut driver, and open-end wrench tooling
• Conforms to ASME B18.6.3 dimensional standards for consistent fitment

Compatibility

Designed as an OEM-style replacement or general-use fastener for any assembly specifying a 1/4-20 UNC fully threaded serrated flange bolt with a 7/8-inch length under head.

Installation Notes

Installation is performed by maintenance technicians and assemblers using standard hex or socket drive tooling sized for a 1/4-20 hex flange bolt. De-energize and lock out any electrical or mechanical equipment before disassembling or replacing fasteners in live assemblies. Do not exceed the torque specification required for Grade 5 hardware in the applicable assembly drawing or service manual. Inspect the mating threaded hole or nut for thread damage before installing; cross-threading will compromise clamping force and vibration resistance.
