Value Collection B10105 Serrated Flange Nut 1/2-20 Zinc-plated

Product Description

The VALUE COLLECTION B10105 is a Grade 2 steel serrated flange nut with a 1/2-20 thread size and a zinc-plated finish. The integrated serrated flange distributes clamping load across a wider bearing surface while the serrations bite into the mating material to resist loosening under vibration. The flange diameter measures 1.031 inches and the flange height measures 0.458 inches. This fastener is suited for mechanical assemblies, structural connections, and general-purpose bolted joints where a standard hex nut with a locking flange is the specified hardware. Each package contains 10 nuts.

This nut is used in residential and light commercial applications wherever a vibration-resistant threaded fastener is required on a 1/2-20 unified fine-thread bolt or stud. Typical install scenarios include equipment mounting, bracket assemblies, and sheet-metal or tubular fabrications. The serrated flange eliminates the need for a separate lock washer, reducing part count and assembly time. Installers in HVAC, plumbing support structures, electrical enclosure fabrication, and general mechanical trades commonly specify this fastener type.

Key Features

• Serrated flange locks against the mating surface under vibration without a separate lock washer
• Grade 2 steel construction provides adequate tensile strength for general-purpose fastening applications
• Zinc-plated finish offers basic corrosion resistance in dry and mildly humid environments
• 1/2-20 unified fine thread for precise torque control and strong thread engagement
• Flange diameter of 1.031 inches spreads clamp load over a larger bearing area
• Package of 10 nuts per order quantity

Compatibility

Designed for use with any 1/2-20 unified fine-thread bolt or stud in standard inch-measurement assemblies requiring a serrated flange nut.

Installation Notes

Install with a standard 3/4-inch hex wrench or socket driver. Ensure the serrated face seats fully and squarely against the mating surface before applying final torque. Do not install on painted or coated surfaces where the serrations are not intended to contact the base material, as clamping performance will be reduced. Power down or de-energize any equipment before performing fastener service on live assemblies.
