Value Collection 825062MSC Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 825062MSC is a serrated flange bolt designed for secure fastening in mechanical, structural, and industrial assembly applications. It features a 1/4-20 UNC thread with a 1-1/2 inch length under the head and is fully threaded from head to end. The integrated serrated flange — measuring 0.56 inches in diameter — bites into the mating surface to resist loosening under vibration without requiring a separate lock washer. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. Installation is performed with a standard hex drive tool.

This serrated flange bolt is suited for general mechanical assembly, HVAC equipment mounting, electrical enclosure assembly, and light structural fastening where vibration resistance is required. The fully threaded shank allows engagement along the entire bolt length, making it practical in thin-material applications and short-clamp-length joints. It is well-suited for both shop assembly and field service work by trade technicians and maintenance professionals.

Key Features

• Serrated flange integrates locking function — eliminates need for a separate lock washer
• Fully threaded shank for maximum thread engagement in thin or short-stack assemblies
• Grade 5 steel construction for reliable tensile and shear strength in mechanical fastening
• Zinc-plated finish provides corrosion resistance in typical indoor and sheltered environments
• Hex drive head compatible with standard wrenches and sockets
• Meets ASME B18.6.3 and SAE J429 dimensional and mechanical standards

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt suitable for use in any application requiring a 1/4-20 UNC fastener with an integrated locking flange and 1-1/2 inch length under head.

Installation Notes

Installation is typically performed by maintenance technicians, electricians, HVAC mechanics, or general trade professionals using a standard hex wrench or socket driver. Ensure the mating surface is clean and flat so the serrated flange seats fully for proper locking action. Do not reuse serrated flange bolts in critical joints once fully torqued, as the serrations may deform the mating surface on removal. Follow applicable industry torque guidelines for 1/4-20 Grade 5 fasteners per the relevant equipment service documentation.
