Value Collection 406334PS Serrated Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 406334PS is a serrated flange bolt designed for secure fastening in structural and mechanical assemblies. It features a 1/2-13 UNC thread size with a fully threaded shank measuring 2-1/2 inches under the head. The integrated serrated flange — ranging from 1.02 to 1.07 inches in diameter — acts as a built-in lock washer, distributing clamp load and resisting loosening under vibration. The bolt is manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish for basic corrosion resistance. It is installed using a standard hex drive and is suited for general-purpose fastening applications across trades and manufacturing.

This bolt is used in a wide range of residential, commercial, and light industrial applications where a reliable anti-vibration fastener is needed without a separate lock washer. Typical install scenarios include mechanical equipment mounting, structural bracketing, HVAC equipment frames, and general assembly work. The fully threaded shank allows for flexible engagement depth across the full bolt length, making it useful in thin-material or through-bolt configurations. This bolt is sold in a minimum order quantity of 5 units.
