Value Collection KP24743 Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION KP24743 is a fully threaded serrated flange bolt designed for secure fastening in structural and mechanical assemblies. It features a 3/8-16 UNC thread with a 1-inch length under the head and a hex drive for standard wrench or socket installation. The integrated serrated flange measures 0.81 inches in diameter and distributes clamping load across a wider bearing surface while the serrations resist loosening under vibration. Manufactured from Grade 5 steel with a zinc yellow dichromate finish, it meets ASME B18.6.3 and SAE J429 standards. This bolt is used by mechanical contractors, maintenance technicians, and assembly professionals across a wide range of industrial and trade applications.

This bolt is suited for general mechanical assemblies, HVAC equipment mounting, electrical enclosure hardware, and light structural connections where vibration resistance is a priority. The serrated flange eliminates the need for a separate lock washer in many applications, simplifying assembly. Sold in a package of 50, it is appropriate for both service technicians stocking their supply and contractors working on multi-unit installations requiring consistent fastener specification.

Compatibility

Designed as a standard 3/8-16 UNC serrated flange bolt suitable for use in any application requiring a Grade 5 fully threaded hex flange fastener conforming to ASME B18.6.3 and SAE J429.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for 3/8-inch fasteners. De-energize and lock out equipment before replacing or installing fasteners in electrical or mechanical systems per applicable safety codes. The serrated flange is intended to seat directly against the mating surface without a separate lock washer; ensure the bearing surface is clean and free of debris for proper seating. Do not exceed the torque rating for Grade 5 hardware as specified in your applicable fastener torque reference.
