Value Collection KP24735 Serrated Flange Bolt 5/16-18 Unc

Product Description

The VALUE COLLECTION KP24735 is a serrated flange bolt designed for secure fastening in mechanical and structural assemblies. It features a 5/16-18 UNC thread form with a 1-inch length under head and is fully threaded from head to tip. The integrated serrated flange distributes clamping load across a wider surface area while the serrations resist loosening from vibration. Drive type is hex, making it compatible with standard wrenches and sockets. The bolt is manufactured from Grade 5 steel and finished in zinc yellow dichromate for corrosion resistance. This package contains 50 pieces. Licensed trades and industrial maintenance professionals will find this a dependable general-purpose fastener.

These serrated flange bolts are suited for residential and light commercial mechanical installations, equipment mounting, and structural connections where a built-in flange eliminates the need for a separate washer. The fully threaded shank allows engagement through the full grip range. Typical applications include HVAC equipment mounting, electrical enclosure assembly, and general sheet metal or structural fabrication work. The zinc yellow dichromate finish adds protection in mildly corrosive environments. This is a sold-by-the-box fastener packaged in quantities of 50 per pack.

Installation Notes

Installation is performed by maintenance technicians, HVAC mechanics, electricians, or general tradespeople using standard hex wrenches or socket drivers. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque range appropriate for Grade 5 steel fasteners of this thread size as specified by applicable job or equipment documentation. When replacing existing hardware, verify thread size and grip length before installing.
