Lockbolt Collar Huck C6L 2LC-F12 3/8 Inch FLNG Alum Plain 100PK

Description

Product Overview

The Huck C6L 2LC-F12 lockbolt collar is engineered to replace traditional welding methods with a fast, reliable, and repeatable fastening solution. Constructed from high‑grade aluminum, the collar meets the FLNG (Flat Lock Nut Groove) standard, providing a uniform clamp that distributes load evenly across the joint. The 3/8 inch (0.375 inch) diameter matches standard pipe and tube sizes, ensuring compatibility with a wide range of industrial components. Its exclusive six‑groove locking design secures the collar in place, delivering a permanent, vibration‑resistant connection that can withstand harsh environmental conditions. Each package contains 100 collars, offering sufficient inventory for large‑scale projects and reducing the need for frequent re‑ordering.

Usage

Designed for versatility, this lockbolt collar excels in HVAC system assemblies, where quick and dependable connections are essential for maintaining airflow integrity. It is equally effective in general manufacturing settings, providing a clean, weld‑free method for joining structural components. Trailer manufacturers benefit from the collar’s lightweight yet strong characteristics, enabling faster build times and easier maintenance. In railroad and transit car construction, the collar’s resistance to vibration and fatigue ensures long‑term reliability, even under the constant stresses of rail operation. The 100‑piece pack is ideal for contractors, fabricators, and maintenance teams who require a ready supply of high‑quality fasteners for ongoing projects.

FAQ

What materials can the lockbolt collar be used with?

The collar is designed for aluminum and steel pipe or tube applications where a non‑welded, permanent joint is required. It works well with common industrial alloys used in HVAC, manufacturing, and transportation.

Is special tooling required for installation?

Installation requires a standard torque wrench or a compatible lockbolt installation tool. No welding equipment or specialized machinery is needed, making the process faster and safer.

How does the six‑groove design improve performance?

The six‑groove pattern distributes clamping force evenly, reducing stress concentrations and preventing loosening under vibration. This results in a more durable and reliable connection over the life of the assembly.

Can the collar be reused after removal?

While the collar is designed for permanent installation, it can be removed with the proper tool if necessary. However, re‑use is not recommended for critical applications, as the locking grooves may experience wear.

What warranty does Huck provide?

Huck offers a limited one‑year warranty covering material defects and manufacturing errors, ensuring that you receive a product that meets the highest standards of quality and performance.
