Value Collection 3110MWW Serrated Flange Bolt 5/16-18 Unc

Product Description

The VALUE COLLECTION 3110MWW is a serrated flange bolt designed for secure fastening in general mechanical and structural assembly applications. The serrated flange face bites into the mating surface as the bolt is driven, providing resistance to loosening from vibration without a separate washer. The bolt is 5/8 inch long under the head, fully threaded with a 5/16-18 UNC coarse thread, and driven by a hex head. It is manufactured from AISI C1022 steel to Grade 2 specifications and finished with a zinc plating for basic corrosion resistance. This fastener is installed by mechanics, maintenance technicians, and assembly workers across light industrial, HVAC, and equipment fabrication settings.

This bolt suits applications where vibration-resistant clamping is needed without adding a separate lock washer. The serrated flange distributes load across a flange diameter of 0.686 to 0.706 inches, making it appropriate for sheet metal, light structural, and equipment panel assemblies. Its fully threaded shank allows clamping across the full grip length, useful in shallow-hole or thin-material installations. Hex drive provides compatibility with standard wrenches and sockets common in trade toolkits.

Key Features

• Serrated flange face provides vibration resistance without a separate lock washer
• Fully threaded shank for maximum clamping flexibility in shallow or thin-material applications
• 5/16-18 UNC coarse thread for fast engagement and broad tool compatibility
• Flange diameter of 0.686 to 0.706 inches distributes clamping load over a wider bearing surface
• Zinc plating provides basic corrosion resistance for indoor and protected outdoor use
• Grade 2 AISI C1022 steel construction meets general-purpose fastener strength requirements

Compatibility

Designed as a general-purpose replacement or stock fastener for any assembly requiring a 5/16-18 UNC serrated flange bolt with a 5/8 inch length under head and fully threaded shank.

Installation Notes

Install with a standard hex wrench or socket driver sized for a 5/16-18 fastener. Ensure mating threads are clean and free of debris before driving. Power down or de-energize any equipment before accessing fastened panels or enclosures. Do not exceed the torque capacity appropriate for Grade 2 steel fasteners in the mating material — consult published torque tables for the specific joint design.
