Value Collection 825148MSC Serrated Flange Bolt 7/16-14 Unc

Product Description

The VALUE COLLECTION 825148MSC is a serrated flange bolt designed for applications requiring a secure, vibration-resistant fastening solution. The integrated serrated flange distributes clamping load across a wider surface area while the serrations bite into the mating material to resist loosening under dynamic or vibratory loads. Manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt carries a 7/16-14 UNC thread and is fully threaded along its 1-1/2 inch length under head. It meets ASME B18.6.3 and SAE J429 standards. Installers in HVAC, mechanical, plumbing, and general trade work reach for this fastener when a separate washer or lock washer is not practical.

This bolt suits a broad range of residential and light commercial assembly and service tasks. The hex drive makes it compatible with standard box-end wrenches, combination wrenches, and impact sockets commonly found on service vans. Fully threaded construction allows engagement along the entire shank, making it useful in thin-material and short-grip applications. The serrated flange face provides built-in locking action without an additional locking element, simplifying assembly in tight or hard-to-reach locations.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Fully threaded along the entire 1-1/2 inch shank for maximum thread engagement in short-grip applications
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides corrosion protection in typical indoor and sheltered outdoor environments
• 0.93 inch flange diameter spreads clamping load and reduces surface damage on softer substrates
• Hex drive compatible with standard 3/4 inch wrenches and sockets

Compatibility

Designed as a standard 7/16-14 UNC serrated flange bolt suitable for general mechanical assembly, equipment mounting, and service replacement applications where Grade 5 steel and fully threaded construction are specified.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using properly sized hand or power tools. Always verify thread engagement and confirm the mating material thread specification matches 7/16-14 UNC before driving the fastener. Apply only the torque appropriate for Grade 5 fasteners of this thread size as defined by the applicable engineering specification or equipment service manual. Do not exceed rated torque, as over-tightening can damage the serrated flange or strip the mating threads.
