Value Collection 825044MSC Serrated Flange Bolt 10-32 Unf

Product Description

The VALUE COLLECTION 825044MSC is a serrated flange bolt designed for secure fastening in mechanical and structural assemblies where a built-in washer surface and vibration resistance are required. The serrated flange distributes load across a 0.454-inch flange diameter while the serrations bite into the mating surface to resist loosening under vibration and dynamic loads. Manufactured from Grade 5 steel with a zinc-plated finish, this bolt meets ASME B18.6.3 and SAE J429 standards. It is fully threaded on a 10-32 UNF shank with 3/4-inch length under the head, driven by a hex drive. This fastener is installed by HVAC technicians, electricians, plumbers, and general mechanical trades.

This bolt is suited for light-duty panel, bracket, and equipment assembly applications where a flanged bearing surface eliminates the need for a separate flat washer. The 10-32 UNF thread pitch is common in sheet metal enclosures, electrical panels, HVAC equipment cabinets, and small machinery frames. The zinc-plated finish provides basic corrosion resistance for indoor and light-exposure environments. Fully threaded construction allows engagement along the full shank length, making it useful in thin-material applications.

Key Features

• Serrated flange with 0.454-inch diameter resists loosening under vibration without a separate washer
• 10-32 UNF fully threaded shank provides maximum thread engagement in thin stock
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish offers corrosion resistance for indoor and sheltered installations
• Conforms to ASME B18.6.3 dimensional standards for consistent fitment
• Hex drive compatible with standard socket and wrench tooling

Compatibility

Designed as a standard 10-32 UNF serrated flange bolt for use in any application requiring an ASME B18.6.3 compliant fastener with a serrated bearing flange.

Installation Notes

Installation requires a hex wrench or socket driver sized for the hex head. Power down or de-energize any equipment before fastening into electrical enclosures or HVAC cabinet panels. Do not exceed the torque capacity appropriate for Grade 5 steel at this thread size as specified by the applicable fastener standard. Zinc-plated fasteners are not rated for outdoor immersion or highly corrosive environments without additional protection.
