Value Collection 825050MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825050MSC is a serrated flange bolt designed for secure fastening in general mechanical and structural assembly applications. It features a 1/4-20 UNC thread pattern with a 3/8-inch length under the head and is fully threaded from head to end. The integrated serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. Installation uses a standard hex drive.

This bolt is suited for light-to-medium duty fastening tasks where vibration resistance is required without a separate lock washer. Common applications include equipment panels, brackets, sheet metal assemblies, HVAC equipment housings, electrical enclosures, and general industrial fabrication. The zinc-plated finish provides baseline corrosion resistance for indoor and mildly exposed environments. The compact 3/8-inch thread length makes it appropriate for thin-stock and close-tolerance assemblies where a longer fastener would bottom out or protrude.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Fully threaded 1/4-20 UNC, 3/8-inch length under head for consistent engagement in thin material
• 0.56-inch flange diameter distributes clamping load over a wider bearing area
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish for baseline corrosion protection
• Hex drive for use with standard wrenches or sockets
• Conforms to ASME B18.6.3 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt suitable for use in any application requiring an ASME B18.6.3 compliant fastener of this thread size and length.

Installation Notes

Installation is performed with a hex wrench or socket driver sized to the flange bolt head. Ensure the mating thread is clean and free of debris before driving. Do not exceed the torque rating appropriate for Grade 5 hardware at this thread size as referenced in fastener torque tables. For structural or safety-critical assemblies, consult applicable mechanical codes and engineering specifications before selecting fastener grade and finish.
