Value Collection 824401MSC Serrated Flange Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 824401MSC is a serrated flange bolt designed for secure, vibration-resistant fastening in industrial and mechanical assemblies. It features a 1/2-13 UNC thread with a 1-1/4 inch length under head and is fully threaded from head to tip. The integrated serrated flange — 1.07 inches in diameter — distributes clamping load and bites into mating surfaces to resist loosening without a separate washer. Manufactured from Grade 5 steel and finished with a zinc plating for basic corrosion resistance, this bolt meets ASME B18.6.3 and SAE J429 standards. Installation requires a standard hex drive tool.

This bolt is suited for general mechanical assembly, structural fastening, and equipment mounting applications where vibration or dynamic loading is a concern. The serrated flange makes it particularly useful in automotive, agricultural, and light industrial equipment where a separate washer is impractical or undesirable. The fully threaded shank provides maximum thread engagement across varying material thicknesses.

Key Features

• 1/2-13 UNC thread, fully threaded for maximum engagement
• 1.07-inch serrated flange eliminates the need for a separate washer and resists loosening under vibration
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish provides basic corrosion protection
• Hex drive head for standard wrench or socket installation
• Conforms to ASME B18.6.3 dimensional standards

Compatibility

Designed as a standard 1/2-13 UNC serrated flange bolt for use in applications requiring ASME B18.6.3 and SAE J429 compliant fasteners in inch-measurement systems.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or mechanical assemblers using a standard hex wrench or socket. Ensure mating threads are clean and free of debris before installation. Do not exceed recommended torque values for Grade 5 fasteners as specified by the applicable equipment service documentation. Zinc plating provides limited corrosion resistance — evaluate environmental suitability before use in high-moisture or chemical-exposure settings.
