Value Collection 5036MWW Serrated Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 5036MWW is a serrated flange bolt designed for secure fastening in structural and mechanical assemblies. It features a 1/2-13 UNC thread, a fully threaded shank measuring 2-1/4 inches length under head, and an integrated serrated flange ranging from 1.02 to 1.07 inches in diameter. The serrated bearing surface bites into the mating material to resist loosening under vibration, eliminating the need for a separate lock washer in many applications. Made from AISI C1022 Grade 2 steel with a zinc-plated finish, this bolt is suited for general-purpose fastening tasks across industrial, mechanical, and construction settings.

This bolt is used in applications where vibration resistance is a priority and a standard hex bolt with a separate washer would be less efficient. The integrated flange distributes the clamping load over a wider area than a standard hex bolt head, making it a common choice in light structural assemblies, equipment mounting, and bracket installations. A hex drive allows installation with standard wrenches or socket sets. This bolt is sold in multiples of 10.

Key Features

• 1/2-13 UNC fully threaded shank, 2-1/4 inches length under head
• Serrated flange from 1.02 to 1.07 inches diameter resists loosening under vibration
• Integrated flange eliminates need for a separate flat washer in many assemblies
• Hex drive for use with standard wrenches or sockets
• Zinc-plated AISI C1022 Grade 2 steel for general-purpose use

Compatibility

Designed as a general-purpose serrated flange bolt for use in standard 1/2-13 UNC threaded applications requiring an integrated flange bearing surface.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 1/2-13 fastener. Ensure mating threads are clean and free of debris before installation. The serrated flange is designed to seat against a flat, smooth surface for maximum grip — avoid installing against curved or painted surfaces where the serrations cannot fully engage. Follow applicable fastener torque guidelines and job-site codes for the specific assembly type.
