Value Collection 825042MSC Serrated Flange Bolt 10-32 Unf

Product Description

The VALUE COLLECTION 825042MSC is a serrated flange bolt designed for secure fastening in applications where a locking connection is required without a separate washer. The bolt features a 10-32 UNF thread with a 5/8 inch length under the head and is fully threaded along its entire shank. The integrated serrated flange measures 0.454 inches in diameter and bites into the mating surface to resist loosening under vibration. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. It is driven with a hex drive and is suited for mechanical assembly, panel mounting, and equipment fabrication work.

This bolt is used in light-to-medium duty mechanical assemblies where a unified fine thread pitch and a self-locking flange face are required. Typical applications include electrical enclosure assembly, HVAC equipment panels, light structural brackets, and general machinery fabrication. The fully threaded design allows for maximum thread engagement across a range of material thicknesses. The zinc-plated finish provides basic corrosion resistance for indoor and sheltered environments.

Key Features

• Serrated flange integrates locking and load-spreading functions without a separate washer
• 10-32 UNF fully threaded shank for maximum thread engagement
• Grade 5 steel construction meets SAE J429 strength requirements
• Zinc-plated finish for corrosion resistance in indoor and sheltered installations
• Hex drive for standard socket or wrench installation
• Conforms to ASME B18.6.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any assembly calling for a 10-32 UNF serrated flange bolt with a 5/8 inch length under head, Grade 5 steel, and zinc-plated finish per ASME B18.6.3 and SAE J429.

Installation Notes

Installation is performed with a standard hex socket or open-end wrench sized for a No. 10 hex head. Ensure mating threads are clean and free of debris before installation. The serrated flange requires direct metal-to-metal contact with the mating surface to function correctly — do not install over a flat washer or non-metallic surface where the serrations cannot engage. Torque to the value specified in the equipment manufacturer's service documentation for Grade 5 fasteners in this thread size.
