Value Collection 824199MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 824199MSC is a serrated flange bolt engineered for secure, vibration-resistant fastening in structural and mechanical assemblies. With a 3/8-16 UNC thread and 3/4 inch length under head, this bolt is fully threaded from the bearing surface to the tip. The integrated serrated flange acts as a built-in washer face, biting into the mating surface to resist loosening under load or vibration. Made from Grade 5 steel with a zinc-plated finish for corrosion resistance, it is driven by a standard hex head. This fastener is installed by maintenance technicians, machinists, and mechanical contractors across a wide range of assembly and repair applications.

This serrated flange bolt is suited for general mechanical assemblies, equipment mounting, and structural connections where positive thread lock without a separate lock washer is needed. The fully threaded shank maximizes thread engagement in thin material applications. It is a practical choice for production line assembly, field repair, and fabrication work where vibration or dynamic loads are present. The zinc plating provides moderate corrosion resistance appropriate for indoor and light-duty outdoor use.

Key Features

• 3/8-16 UNC thread with 3/4 inch length under head, fully threaded
• Serrated flange integrates washer face and locking serrations in one piece, eliminating a separate lock washer
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides corrosion resistance for general-purpose service
• Hex drive accepts standard 9/16 inch wrenches and sockets
• Conforms to ASME B18.6.3 and SAE J429 dimensional and material standards

Compatibility

Designed as a standard inch-series serrated flange bolt for use in any application requiring a 3/8-16 UNC fastener with an integrated serrated flange bearing surface.

Installation Notes

Install using a standard 9/16 inch hex wrench or socket driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque capacity appropriate for Grade 5 fasteners at this thread size as specified by the applicable assembly standard. Follow all applicable mechanical codes and assembly torque specifications provided by the equipment manufacturer.
