Value Collection 406330PS Serrated Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 406330PS is a serrated flange bolt designed for fastening applications that require both clamping force and resistance to loosening under vibration. The integrated serrated flange distributes load across a wider bearing surface, eliminating the need for a separate washer in most applications. Manufactured from AISI C1022 steel with a zinc-plated finish, this bolt carries a Grade 2 material rating. Thread size is 1/2-13 UNC, fully threaded over a 2-inch length under head, with a hex drive for standard wrench or socket installation. Tradespeople and assembly technicians working on structural, mechanical, or equipment-mounting tasks will find this a straightforward general-purpose fastener.

This serrated flange bolt is suited for use in light-to-medium structural assemblies, equipment mounting, and general mechanical fastening in both residential and commercial settings. The fully threaded configuration allows engagement along the entire shank length, making it useful in applications where thread engagement depth varies or where the bolt passes through thinner materials. The zinc plating provides basic corrosion resistance appropriate for indoor and sheltered outdoor environments. It is commonly installed by HVAC technicians, plumbers, electricians, and general mechanical contractors as part of equipment support and enclosure work.

Key Features

• Fully threaded 1/2-13 UNC shank over 2 inches under head for flexible thread engagement
• AISI C1022 steel construction rated at Grade 2
• Zinc-plated finish for basic corrosion protection in sheltered environments
• Hex drive compatible with standard wrenches and sockets
• Flange diameter ranges from 1.02 to 1.07 inches for consistent bearing surface coverage

Compatibility

Designed as a general-purpose 1/2-13 UNC serrated flange bolt suitable for standard inch-system fastening applications in mechanical, HVAC, plumbing, and electrical equipment installations.

Installation Notes

Installation should be performed with a properly sized hex wrench or socket driver rated for the fastener grade. Ensure mating threads are clean and free of debris before installation. The serrated flange is designed to bite into the mating surface to resist backing out — avoid installing against hardened or coated surfaces where the serrations cannot seat properly. Follow applicable mechanical and structural codes for torque requirements based on joint design and material.
