Value Collection 1406MWW Serrated Flange Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 1406MWW is a serrated flange bolt designed for secure fastening in applications where vibration resistance is required. It features a 1/4-20 UNC thread with a 3/8 inch length under head and is fully threaded from the bearing surface to the tip. The integrated serrated flange distributes clamping load across a wider surface area and bites into the mating material to resist loosening under dynamic loads. Manufactured from AISI C1022 steel to Grade 2 specification and finished with a zinc plating for basic corrosion protection, this bolt suits general-purpose mechanical and structural assembly work.

This bolt is suited for light- to medium-duty fastening tasks in residential and commercial maintenance, HVAC equipment assembly, electrical panel work, and general trade applications. The hex drive allows installation with standard hex wrenches or socket sets. The serrated flange eliminates the need for a separate lock washer, reducing hardware count and assembly time. It is commonly used wherever a compact, vibration-resistant fastener is needed in confined spaces or thin-material assemblies.

Key Features

• Serrated flange provides built-in vibration resistance without a separate lock washer
• Fully threaded 1/4-20 UNC shank for maximum thread engagement across short grip lengths
• Flange diameter of 0.513 to 0.531 inches for broad load distribution
• Grade 2 AISI C1022 steel construction for reliable general-purpose strength
• Zinc-plated finish offers basic corrosion protection in indoor and sheltered environments
• Hex drive compatible with standard wrenches and socket sets

Compatibility

Designed as a general-purpose 1/4-20 UNC serrated flange bolt suitable for standard inch-thread fastening applications across HVAC, electrical, plumbing, and mechanical assembly work.

Installation Notes

Installation should be performed by a qualified tradesperson using an appropriate hex wrench or socket. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the rated torque range for Grade 2 fasteners of this thread size, and avoid using impact drivers at high torque settings that may strip threads or damage the flange serrations. Always follow applicable mechanical codes and equipment manufacturer torque guidelines.
