Value Collection 1436MWW Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 1436MWW is a serrated flange bolt manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish. It features a 1/4-20 UNC thread pattern and a 2-1/4 inch length under head, fully threaded from bearing surface to tip. The integrated serrated flange measures 0.513 to 0.531 inches in diameter and functions as a built-in locking washer, biting into the mating surface to resist loosening under vibration. This fastener is driven with a standard hex driver or wrench. Maintenance techs, HVAC installers, plumbers, and general tradespeople stock this bolt for everyday mechanical assembly and equipment mounting applications.

This serrated flange bolt suits residential and light commercial applications where vibration-resistant fastening is needed without a separate lock washer. Common uses include panel mounting, bracket attachment, ductwork supports, equipment frames, and general mechanical assemblies. The fully threaded shank allows maximum thread engagement across the full grip length, making it practical for thin-material applications and through-bolt configurations. Minimum order quantity is 25 pieces per order, sold as individual units.

Key Features

• Serrated flange acts as an integrated locking washer, resisting loosening under vibration
• 1/4-20 UNC fully threaded shank provides maximum thread engagement across the full length
• AISI C1022 Grade 2 steel construction meets standard fastener material requirements
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered applications
• Hex drive compatible with standard sockets, wrenches, and hex-bit drivers
• Flange diameter of 0.513 to 0.531 inches distributes clamping load over a wider bearing surface

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt suitable for general mechanical assembly, equipment mounting, and structural fastening applications where inch-series unified coarse thread fasteners are specified.

Installation Notes

Power down or de-energize any equipment before replacing or installing fasteners in electrical or mechanical assemblies. Drive with a properly sized hex socket or wrench to avoid rounding the head. The serrated flange requires firm, even torque to fully engage the locking teeth against the mating surface. Do not use with soft or coated surfaces where the serrations may cause unacceptable marring.
