Value Collection 824207MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 824207MSC is a serrated flange bolt designed for secure fastening in structural and mechanical assemblies. Sized at 3/8-16 UNC with a 1-inch length under head and fully threaded shank, this bolt integrates a built-in serrated flange that bites into the mating surface to resist loosening under vibration. The 0.81-inch flange diameter distributes clamping load without a separate washer. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. Driven with a standard hex tool, it suits high-volume production and maintenance applications across HVAC, electrical, and general mechanical trades.

This bolt is suited for residential and light commercial assembly work where vibration resistance is a priority. The serrated flange design is commonly specified in HVAC equipment mounting, electrical panel assembly, and mechanical equipment brackets. It is fully threaded, making it useful in short-grip applications where maximum thread engagement is needed. The zinc-plated finish provides baseline corrosion resistance for indoor and sheltered outdoor environments. Technicians and assemblers in the HVAC, plumbing, and electrical trades will find this fastener fits standard 3/8-inch clearance holes in sheet metal and fabricated steel components.

Key Features

• Serrated flange locks against mating surface to resist vibration-induced loosening
• Fully threaded 1-inch shank maximizes thread engagement in short-grip applications
• 0.81-inch flange diameter distributes load and eliminates the need for a separate washer
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides corrosion resistance for indoor and sheltered use
• Hex drive compatible with standard sockets and wrenches

Compatibility

Designed as a standard 3/8-16 UNC serrated flange bolt for use in applications requiring ASME B18.6.3 and SAE J429 compliant fasteners in Grade 5 steel.

Installation Notes

Install using a hex socket or open-end wrench sized for a standard 3/8-16 hex flange bolt head. Ensure the mating surface is clean and flat so the serrated flange seats fully and engages the substrate. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Follow applicable torque guidelines per SAE J429 Grade 5 specifications and relevant assembly codes for the application.
