Value Collection R52001063 Flange Bolt 1/4-20 Unc 1-1/2 in

Product Description

The VALUE COLLECTION R52001063 is a 1/4-20 UNC hex drive flange bolt designed for general fastening applications in mechanical, electrical, and industrial assembly work. It features a 1-1/2 inch length under head with full thread engagement along the entire shank. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Manufactured from Grade 2 AISI C1022 steel with a zinc-plated finish, this bolt offers corrosion resistance suitable for indoor and light-duty service environments. Installed using a standard hex drive bit or wrench, it suits maintenance technicians, electricians, and general trade professionals working with panel assemblies, brackets, and equipment mounting.

This flange bolt is appropriate for light structural and equipment fastening tasks across residential, commercial, and industrial settings. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes in North American trade work, making this bolt a practical stock item for panel mounting, conduit clamps, bracket hardware, and general assembly. The serrated flange eliminates the need for a separate lock washer in many applications, reducing hardware count and installation time. Sold individually with a minimum order quantity of 50 units, making it well suited for stocking in service vans or supply rooms.

Key Features

• 1/4-20 UNC thread form with fully threaded shank for maximum engagement
• Serrated flange provides built-in vibration resistance, replacing a separate lock washer
• Flange diameter between 0.513 and 0.531 inches for broad clamping surface coverage
• Grade 2 AISI C1022 steel construction for reliable mechanical strength in light-duty use
• Zinc-plated finish for corrosion protection in indoor and dry environments
• Hex drive head compatible with standard hex bits and wrenches for fast installation

Compatibility

Designed as a general-purpose 1/4-20 UNC fully threaded flange bolt suitable for standard tapped holes and nuts conforming to unified coarse thread specifications in light mechanical and electrical assembly applications.

Installation Notes

Installation should be performed by qualified trade personnel following applicable codes such as NEC for electrical assemblies or relevant mechanical standards. Verify thread engagement with the mating nut or tapped hole before applying torque. The serrated flange requires a clean, flat bearing surface to function correctly. Do not use this fastener in applications requiring Grade 5 or Grade 8 rated hardware where higher strength is specified.
