Value Collection 3714MWW Serrated Flange Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 3714MWW is a serrated flange bolt designed for secure fastening in general mechanical and structural assemblies. Threaded to the 3/8-16 UNC standard with a fully threaded shank measuring 7/8 inches under the head, this bolt integrates a built-in serrated flange that bites into the mating surface to resist loosening under vibration. The hex drive allows installation with standard wrenches or sockets. Manufactured from AISI C1022 Grade 2 steel with a zinc-plated finish, it provides corrosion resistance suitable for indoor and light-duty outdoor applications. Licensed tradespeople and maintenance technicians across HVAC, plumbing, and general mechanical trades routinely use this fastener type in equipment mounting and panel assembly work.

This bolt is appropriate for use in residential and light commercial applications where a vibration-resistant fastener is required without the need for a separate lock washer. The serrated flange distributes clamping load across a wider bearing area while the serrations grip the workpiece surface. Typical scenarios include mounting brackets, equipment frames, electrical enclosures, and mechanical assemblies that experience operational vibration. The fully threaded configuration makes it well suited for shorter through-bolt applications and thin-material clamping situations.

Key Features

• 3/8-16 UNC fully threaded shank, 7/8 inches length under head
• Serrated flange diameter of 0.771 to 0.793 inches resists loosening under vibration without a separate lock washer
• Hex drive compatible with standard wrenches and socket sets
• AISI C1022 Grade 2 steel construction with zinc-plated finish for corrosion resistance
• Wider flange bearing surface distributes clamping load across the joint

Compatibility

Designed as a standard 3/8-16 UNC serrated flange bolt suitable for general mechanical, structural, and equipment-mounting applications requiring a vibration-resistant fastener in the 7/8-inch length-under-head range.

Installation Notes

Install with a standard hex wrench or socket driver sized for the bolt head. Ensure mating surfaces are clean and free of debris so the serrated flange can seat properly against the workpiece. Shut down and de-energize any equipment before performing fastener service on electrical enclosures or energized assemblies. Do not reuse a serrated flange bolt after removal, as the serrations may not re-engage the mating surface with adequate grip.
