Value Collection 1420MWW Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 1420MWW is a serrated flange bolt with a 1/4-20 UNC thread and a 1-1/4 inch length under the head. The serrated flange bearing surface bites into the mating material to resist loosening under vibration without a separate lock washer. The bolt is fully threaded along its 1-1/4 inch shank and features a standard hex drive. It is manufactured from AISI C1022 Grade 2 steel and finished with a zinc plating for basic corrosion resistance. Maintenance technicians, HVAC installers, electricians, and general contractors use this fastener for light-duty panel, bracket, and sheet-metal assembly work.

This fastener is suited for residential and light commercial applications where a self-locking flange bolt is needed in confined or vibration-prone assemblies. The hex drive is compatible with standard wrenches and sockets. The fully threaded shank provides maximum thread engagement across the full grip length, making it practical for thin-material and short-grip installations. Minimum order quantity is 50 pieces, supplied as individual units per package.

Key Features

• Serrated flange bearing surface resists loosening under vibration without a separate lock washer
• Fully threaded 1/4-20 UNC shank provides complete thread engagement over the full 1-1/4 inch length under head
• Flange diameter of 0.513 to 0.531 inches distributes clamping load across a wider bearing area
• AISI C1022 Grade 2 steel construction suitable for light-duty structural and mechanical assembly
• Zinc-plated finish provides basic corrosion protection in dry indoor environments
• Hex drive is compatible with standard open-end, box, and socket wrenches

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt for use in any application requiring a 1/4-inch coarse-thread fastener with an integrated locking flange.

Installation Notes

Installation does not require a separate flat washer or lock washer due to the integrated serrated flange. Power down or de-energize any equipment before fastening components in electrical or HVAC panels. Use a properly sized hex wrench or socket to avoid rounding the drive. Do not exceed the torque capacity appropriate for Grade 2 fasteners in the base material being fastened.
