Value Collection KP24730 Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION KP24730 is a serrated flange bolt designed for fastening applications where vibration resistance and a flush bearing surface are required. The bolt features a 1/4-20 UNC thread profile and is fully threaded along its 2-inch length under head, providing maximum thread engagement across the full fastener body. The integrated flange measures 0.56 inches in diameter and includes serrations on the underside to resist loosening under dynamic or vibratory loads. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt conforms to ASME B18.6.3 and SAE J429 standards. It is sold in a package of 50.

This serrated flange bolt is suited for general mechanical assembly, equipment mounting, and structural fastening in both light industrial and commercial settings. The hex drive allows installation with standard hex wrenches or power drivers. The serrated flange eliminates the need for a separate lock washer in most applications, reducing hardware count and assembly time. Typical applications include sheet metal assemblies, HVAC equipment panels, electrical enclosures, and mechanical frameworks where controlled clamping load and vibration resistance are priorities.

Installation Notes

Installation is performed by mechanics, millwrights, or trade professionals using a hex wrench or socket driver sized for the head. Power down and de-energize any equipment before accessing fastened panels or assemblies. Ensure mating threads are clean and free of debris before driving the bolt. Do not exceed the torque limits specified by the equipment manufacturer for 1/4-20 Grade 5 fasteners.
