Value Collection 1444MWW Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 1444MWW is a serrated flange bolt designed for secure fastening in applications where a built-in locking surface is required. Threaded to the 1/4-20 UNC standard with a full thread length of 2-3/4 inches under the head, this bolt uses a hex drive for standard wrench or socket installation. The serrated flange distributes load across the bearing surface and bites into the mating material to resist loosening from vibration. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, it balances moderate tensile strength with basic corrosion protection for general-purpose use.

This serrated flange bolt is suited for light to medium-duty mechanical assemblies in HVAC equipment, electrical enclosures, equipment panels, ductwork brackets, and similar trade applications where vibration resistance is a priority. The fully threaded shank provides maximum thread engagement across a range of material thicknesses. The zinc-plated finish offers adequate protection in dry or mildly corrosive indoor environments. Installation requires only a standard hex wrench or socket and no separate lock washer is needed due to the integral serrated flange.

Key Features

• Serrated flange provides integral vibration-resistant locking — no separate lock washer required
• Fully threaded 2-3/4 inch shank allows maximum thread engagement across varying material thicknesses
• 1/4-20 UNC thread standard for broad compatibility with standard nuts, inserts, and tapped holes
• Hex drive accepts standard wrenches and sockets for fast installation and removal
• AISI C1022 Grade 2 steel construction with zinc-plated finish for general indoor use

Compatibility

Designed as a standard 1/4-20 UNC serrated flange bolt for use with any tapped hole, nut, or threaded insert conforming to the UNC inch fastener standard.

Installation Notes

Installation is performed with a standard hex wrench or socket matching the bolt head size. De-energize and lock out any equipment before fastening or removing hardware on electrical or mechanical assemblies per applicable OSHA lockout/tagout procedures. Do not exceed the torque rating appropriate for Grade 2 steel at this thread size — consult a standard fastener torque chart for the correct value. Inspect the mating surface and threads for damage before installation to ensure proper seating of the serrated flange.
