Value Collection 825072MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825072MSC is a serrated flange bolt designed for general fastening applications where a built-in locking flange eliminates the need for a separate washer. The serrated underside of the flange bites into the mating surface to resist loosening under vibration and dynamic loads. At 3 inches in length under head with a 1/4-20 UNC thread form and fully threaded shank, this bolt suits medium-duty clamping tasks across a wide range of assemblies. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards for dimensional and mechanical compliance.

This bolt is used in light to medium structural and mechanical assembly work across trades including HVAC equipment mounting, electrical enclosure fabrication, plumbing fixture installation, and general sheet metal work. The fully threaded shank provides maximum thread engagement even in shallow clearance applications, and the hex drive head is compatible with standard hand tools and power drivers. The zinc plating provides baseline corrosion resistance suitable for indoor and protected outdoor environments.

Key Features

• Serrated flange eliminates the need for a separate lock washer and resists loosening under vibration
• Fully threaded shank maximizes thread engagement throughout the 3-inch length
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish provides corrosion resistance for general service environments
• Hex drive head compatible with standard sockets, wrenches, and power drivers
• Conforms to ASME B18.6.3 dimensional standards for consistent fitment

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt suitable for use in any application calling for a 1/4-20 hex flange bolt per ASME B18.6.3 and SAE J429 specifications.

Installation Notes

Install using a standard hex socket or open-end wrench sized for a 1/4-20 flange bolt head. Ensure mating surfaces are clean and free of debris so the serrations can seat properly against the work surface. Do not use an additional flat washer under the flange, as this will defeat the serrated locking feature. Follow applicable torque guidelines per SAE J429 Grade 5 specifications for the fastener diameter.
