Value Collection 825114MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 825114MSC is a serrated flange bolt designed for secure fastening in applications where a built-in flange replaces the need for a separate washer. The serrated underside of the flange bites into the mating surface to resist loosening under vibration and dynamic loads. This bolt features a 3/8-16 UNC thread, a fully threaded shank with 5/8 inch length under head, and an 0.81 inch flange diameter. Constructed from Grade 5 steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J429 standards. Licensed trades and industrial assembly technicians use these bolts in mechanical, structural, and equipment-mounting applications.

This serrated flange bolt is suited for general mechanical assembly, equipment mounting, and structural connections where vibration resistance is a priority. The fully threaded shank allows engagement along the entire length under head, making it effective in shallow blind holes and thin-material applications. The zinc-plated finish provides a basic level of corrosion resistance for indoor and sheltered installations. It is appropriate for residential, commercial, and light industrial environments where Grade 5 strength requirements apply.

Key Features

• Serrated flange underside resists loosening under vibration without a separate washer
• Fully threaded shank maximizes thread engagement in shallow or thin-material installations
• Grade 5 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides basic corrosion protection for sheltered environments
• Conforms to ASME B18.6.3 dimensional standards for consistent fitment
• Hex drive for use with standard wrenches and sockets

Compatibility

Designed as a standard 3/8-16 UNC serrated flange bolt suitable for use wherever Grade 5 hex flange fasteners conforming to ASME B18.6.3 and SAE J429 are specified.

Installation Notes

Install using a standard hex wrench or socket rated for the fastener size. Ensure mating threads are clean and free of debris before installation. Do not exceed torque values specified by the joint design or equipment manufacturer for Grade 5 fasteners of this thread size. Zinc-plated fasteners are intended for dry or sheltered environments and are not a substitute for corrosion-resistant grades in wet or chemical-exposure conditions.
