Value Collection 825038MSC Serrated Flange Bolt 10-32 Unf

Product Description

The VALUE COLLECTION 825038MSC is a serrated flange bolt designed for secure fastening in applications where a built-in locking flange eliminates the need for a separate washer. Sized at 10-32 UNF with a 3/8 inch length under head and fully threaded shank, this hex-drive fastener provides consistent clamp load and vibration resistance through its serrated flange bearing surface. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion protection, it meets ASME B18.6.3 and SAE J429 standards. Electricians, HVAC technicians, and general mechanical assemblers commonly install this bolt in panel, bracket, and equipment enclosure applications.

This fastener is suited for light- to medium-duty mechanical assemblies in both residential and commercial settings. The 10-32 UNF thread pitch is a standard fine-thread specification common in electrical enclosures, HVAC equipment panels, control boards, and sheet metal assemblies. 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. It installs with a standard hex driver or wrench and requires no separate lock washer or flat washer in typical applications.

Key Features

• 10-32 UNF fully threaded shank provides fine-thread engagement for secure clamping in thin or tapped material
• Serrated flange bearing surface resists loosening under vibration without a separate washer
• 0.454 inch flange diameter spreads clamping load across a wider surface area
• Grade 5 steel construction meets SAE J429 mechanical requirements for medium-strength fasteners
• Zinc-plated finish provides baseline corrosion resistance for indoor and protected installations
• Hex drive compatible with standard hex keys, nut drivers, and wrenches

Compatibility

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

Installation Notes

This fastener is installed by general mechanics, electricians, and HVAC technicians using a hex driver or appropriately sized wrench. Always de-energize and lock out equipment before accessing electrical enclosures or control panels. Verify thread engagement depth and confirm the mating tapped hole or nut matches the 10-32 UNF thread specification before installation. Do not overtighten in thin sheet metal applications, as the serrated flange can damage soft substrates.
