Value Collection 825350MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 825350MSC is a serrated flange bolt designed for high-strength fastening applications where a built-in locking mechanism is required. This bolt features a 3/8-16 UNC thread with a 1-inch length under head and is fully threaded along its entire shank. The integrated serrated flange distributes clamping load across a wider surface area while the serrations bite into the mating material to resist loosening under vibration. Made from Grade 8 steel with a zinc-plated finish, it is suited for demanding mechanical and structural assemblies. Licensed tradespeople and maintenance professionals working with heavy equipment, automotive, and structural steel installations rely on this type of fastener.

This serrated flange bolt is appropriate for use in industrial, commercial, and mechanical assembly applications where vibration resistance is critical. The 3/8-16 UNC thread is a common size in automotive, HVAC equipment frames, electrical enclosure mounting, and general structural fabrication. The fully threaded design maximizes thread engagement in thin materials or shorter joint stacks. The hex drive allows use with standard box-end wrenches and hex sockets. This bolt is sold individually but carries a minimum order quantity of 100 pieces, making it suitable for stocking in a shop, service van, or production environment.

Key Features

• Serrated flange resists loosening under vibration without a separate lock washer
• Fully threaded shank maximizes thread engagement throughout the joint
• Grade 8 steel construction provides high tensile and shear strength
• Zinc-plated finish offers corrosion resistance in standard indoor and sheltered environments
• Hex drive compatible with standard sockets and wrenches
• Meets ASME B18.6.3 and SAE J429 standards for dimensional and mechanical conformance

Compatibility

Designed as an OEM-style replacement or stock fastener for applications requiring a 3/8-16 UNC serrated flange bolt with a 1-inch length under head and a fully threaded shank in Grade 8 steel.

Installation Notes

Installation is performed with a hex socket or box-end wrench sized for the standard 3/8-inch hex flange bolt head. Ensure mating threads are clean and free of debris before installation. The serrated flange is designed to seat directly against the workpiece surface — do not use a flat washer between the flange and the mating surface, as this will defeat the anti-loosening serrations. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for Grade 8 hardware.
