Value Collection 5012MWW Serrated Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 5012MWW is a serrated flange bolt designed for general fastening applications where vibration resistance and load distribution are required. The integrated serrated flange acts as a built-in washer, spreading the clamping load across a wider surface area while the serrations bite into the mating material to resist loosening under vibration. The bolt is fully threaded to 1/2-13 UNC with a length under head of 3/4 inches and a flange diameter ranging from 1.02 to 1.07 inches. Manufactured from AISI C1022 steel to Grade 2 specification and finished with a zinc plating for basic corrosion resistance, this bolt is driven by a standard hex head.

Serrated flange bolts in this size range are commonly used in light structural assemblies, HVAC equipment mounting, electrical enclosure fabrication, and general mechanical assembly across residential and commercial applications. The 1/2-13 UNC thread is a widely used coarse-thread standard, making this bolt compatible with standard UNC tapped holes and nuts of the same thread designation. This style is particularly useful in sheet metal and thin-material assemblies where a separate washer is impractical or would be lost during assembly.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Flange diameter of 1.02 to 1.07 inches distributes clamping load over a wider bearing surface
• Fully threaded 1/2-13 UNC coarse thread for maximum engagement in shallow or thin materials
• AISI C1022 steel, Grade 2, for general-purpose structural fastening
• Zinc-plated finish for basic corrosion protection in indoor and sheltered environments
• Hex drive compatible with standard wrenches and sockets

Compatibility

Designed for use in standard 1/2-13 UNC tapped holes and with 1/2-13 UNC hex nuts across general mechanical, HVAC, electrical, and structural assembly applications.

Installation Notes

Installation is performed using a standard hex wrench or socket set sized for the bolt head. Ensure the mating threads are clean and free of debris before installation. Do not exceed the torque capacity appropriate for Grade 2 fasteners in the material being fastened. For outdoor or high-moisture environments, consider a higher-grade corrosion-resistant finish, as zinc plating provides limited protection in exposed conditions.
