Value Collection 825352MSC Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 825352MSC is a fully threaded serrated flange bolt designed for high-strength mechanical fastening in industrial and structural assemblies. Built to Grade 8 steel with a zinc-plated finish, it delivers elevated tensile strength and corrosion resistance in a single fastener. The serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. Thread size is 3/8-16 UNC with a 1-1/4 inch length under head, making it a common choice for medium-duty bolted connections where a washer-free installation is preferred.

This bolt is suited for mechanical, automotive, equipment fabrication, and general industrial applications where vibration resistance and positive locking without a separate washer are required. The hex drive accepts standard hex sockets and wrenches, streamlining installation in production or field environments. Fully threaded construction allows maximum thread engagement across the full clamped length. Manufactured to ASME B18.6.3 and SAE J429 standards, this fastener is appropriate for use in structural bolted joints, mounting brackets, and equipment frames across light and heavy industrial settings.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Serrated flange integrates a built-in locking washer face, eliminating a separate washer in many applications
• Zinc-plated finish provides corrosion resistance in moderate-exposure environments
• Fully threaded 3/8-16 UNC shank for maximum thread engagement over the 1-1/4 inch grip length
• Hex drive compatible with standard 9/16 inch hex sockets and wrenches
• Conforms to ASME B18.6.3 and SAE J429 for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style replacement or new-installation fastener for any bolted assembly requiring a 3/8-16 UNC Grade 8 serrated flange bolt with 1-1/4 inch length under head.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or mechanical assemblers using a standard hex socket or combination wrench. Always de-energize and lock out equipment before servicing fastened assemblies on powered machinery. The serrated flange face should seat directly against the mating surface without an additional washer unless the base material is too soft to resist flange embedment. Verify that thread engagement depth meets applicable structural or equipment OEM requirements before final torque.
