Value Collection 4324MWW Serrated Flange Bolt 7/16-14 Unc

Product Description

The VALUE COLLECTION 4324MWW is a serrated flange bolt designed for secure mechanical fastening in assemblies where vibration resistance and load distribution are critical. It features a 7/16-14 UNC thread profile with a 1-1/2 inch length under the head and is fully threaded from tip to flange. The integrated serrated flange eliminates the need for a separate lock washer by biting into the mating surface to resist loosening. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, it offers basic corrosion resistance suitable for general industrial and mechanical applications. A licensed mechanic, millwright, or maintenance technician typically installs this fastener using standard hex tooling.

This bolt is used across a wide range of general-purpose fastening applications including HVAC equipment frames, sheet metal assemblies, light structural connections, and mechanical equipment mounting. The serrated flange face distributes clamping load over a wider area than a standard hex bolt, reducing the chance of surface deformation on softer substrates. It is appropriate for residential and light commercial applications where a Grade 2 fully threaded fastener meets the design specification.

Key Features

• 7/16-14 UNC thread for compatibility with standard inch-series tapped holes and nuts
• Fully threaded along the full 1-1/2 inch length under head for maximum thread engagement
• Serrated flange face provides vibration-resistant locking without a separate washer
• Flange diameter of 0.856 to 0.930 inches distributes clamping load over a wider bearing surface
• AISI C1022 Grade 2 steel construction meets standard mechanical fastener material requirements
• Zinc-plated finish provides basic corrosion protection for general indoor and sheltered applications

Compatibility

Designed as a general-purpose inch-series serrated flange bolt suitable for standard 7/16-14 UNC tapped holes and hex nuts across light mechanical, HVAC, and industrial assembly applications.

Installation Notes

Installation requires a standard hex driver or wrench sized for a 7/16-14 UNC bolt head. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque range appropriate for Grade 2 fasteners as specified by the equipment manufacturer or applicable industry standards. The serrated flange must seat directly against the workpiece surface to function as intended — do not install with a flat washer between the flange and the mating surface.
