Value Collection 825116MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 825116MSC is a serrated flange bolt designed for secure fastening in mechanical and structural assemblies. It features a 3/8-16 UNC thread with a 7/8 inch length under head and is fully threaded from bearing surface to tip. The integrated serrated flange distributes clamping load across a wider 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. It is installed using a standard hex drive and suits applications where a separate washer would be impractical or undesirable.

This bolt is commonly used in automotive, industrial equipment, sheet metal, and general mechanical assembly applications where vibration resistance is a priority. The serrated flange face provides built-in locking action without requiring a secondary locking element. The compact 7/8 inch length makes it well suited for shallow boss or close-clearance installations requiring a fully threaded grip.

Key Features

• Serrated flange integrates washer function and vibration-resistant locking in a single fastener
• Fully threaded 3/8-16 UNC shank for maximum thread engagement in shallow applications
• 0.81 inch flange diameter distributes clamping load over a broader bearing area
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides corrosion resistance for general-service environments
• Hex drive for installation with standard wrenches or sockets

Compatibility

Designed as a standard 3/8-16 UNC serrated flange bolt suitable for use in any application requiring an ASME B18.6.3 compliant hex flange fastener of this thread size and length.

Installation Notes

Serrated flange bolts are installed by general mechanics, maintenance technicians, and assemblers using standard hex wrenches or sockets. Ensure the mating surface is clean and free of debris so the serrations can seat properly and provide effective locking action. Do not use with soft or coated mating materials where serration marking is unacceptable. Follow applicable torque specifications for 3/8-16 Grade 5 fasteners as defined by the relevant assembly or equipment standard.
