Value Collection 1414MWW Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 1414MWW is a serrated flange bolt designed for secure fastening in applications where a locking function is needed without a separate washer. The integrated serrated flange bites into the mating surface under torque, resisting loosening from vibration. Sized at 1/4-20 UNC with a 7/8-inch length under head and fully threaded shank, this bolt is manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish for basic corrosion resistance. It is a standard inch-system fastener suited for general mechanical assembly, light structural, and equipment maintenance applications.

This bolt is appropriate for general-purpose fastening in residential and light commercial equipment assembly, maintenance, and repair. The 1/4-20 UNC thread is one of the most common thread forms in inch-standard mechanical assemblies, making this bolt a frequent replacement or stock item across HVAC equipment panels, electrical enclosures, and plumbing fixture brackets. The serrated underside of the flange is particularly useful in vibration-prone environments where a split lock washer would otherwise be required.

Key Features

• Serrated flange distributes clamping load and resists loosening under vibration without a separate washer
• Fully threaded 7/8-inch shank allows maximum engagement in thin or shallow threaded holes
• 1/4-20 UNC thread form for compatibility with standard inch-system tapped holes and nuts
• Flange diameter of 0.513 to 0.531 inches provides a broad bearing surface relative to bolt diameter
• Zinc-plated finish offers basic corrosion protection for indoor and light-duty outdoor use
• Grade 2 AISI C1022 steel construction for standard-duty mechanical fastening

Compatibility

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

Installation Notes

Installation is performed with a standard hex driver or wrench sized for the bolt head. Ensure the mating surface is clean and free of debris so the serrated flange seats properly and achieves its locking function. Do not reuse a serrated flange bolt in the same tapped hole after removal, as the serrations may not re-engage reliably.
