Value Collection 825094MSC Serrated Flange Bolt 5/16-18 Unc

Product Description

The VALUE COLLECTION 825094MSC is a serrated flange bolt designed for secure fastening in applications where vibration resistance is required. It features a 5/16-18 UNC thread and is fully threaded along its 1-1/2 inch length under head. The integrated serrated flange distributes clamp load across a wider bearing surface and bites into the mating material to resist loosening under dynamic loads. Made from Grade 5 steel with a zinc-plated finish for corrosion resistance, this bolt meets ASME B18.6.3 and SAE J429 standards. It is driven with a standard hex wrench or socket. Tradespeople across HVAC, plumbing, electrical, and general mechanical work will find this fastener appropriate for panel, bracket, and equipment mounting tasks.

This bolt is suited for use in light- to medium-duty structural and mechanical assemblies where a flanged bearing surface and anti-loosening serrations are needed. Typical install scenarios include mounting sheet metal brackets, equipment frames, electrical enclosures, and mechanical components where a separate washer is undesirable or impractical. The hex drive makes it compatible with standard socket sets and wrenches. This product is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Serrated flange locks against mating surface to resist vibration-induced loosening
• Fully threaded 1-1/2 inch length under head provides maximum thread engagement
• 0.68 inch flange diameter distributes clamp load without a separate washer
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish provides corrosion protection in general service environments
• Conforms to ASME B18.6.3 dimensional standards for hex flange bolts

Compatibility

Designed as a standard inch-series serrated hex flange bolt for use in any application requiring a 5/16-18 UNC fully threaded fastener with an integrated flanged bearing surface.

Installation Notes

Install using a standard hex socket or open-end wrench sized for a 5/16-18 UNC hex head fastener. Ensure mating threads are clean and free of debris before installation. Torque to the value specified in the relevant equipment service manual or applicable fastener standard for Grade 5 hardware. Do not reuse fasteners that show signs of thread damage, corrosion, or deformation of the serrated flange.
