Spire Clips

Metrol Motion Control supplies a broad range of spring nuts and spire clips for industrial uses such as machine design, building installation and many other applications. Spire clips and speed clips are essential to securing various installed elements and are most commonly found in automotive applications.

Chimney Nuts

Chimney nuts are highly adaptable and used in many different applications. These nuts are easily identified by their deep threat form fastener. In addition, the inbuilt multiple-thread form provides a stronger fixing than alternative spring steel U nuts, which employ self-tapping screws with only a single thread engaged. Compared to U clip nuts, the benefit of multiple threads is clear. They can provide greater torque for the clamp load and maintain a more robust and secure joint.

Channel Nuts

Channel nuts are used with specialised support systems to create a robust infrastructure. Despite being designed for multiple applications, these nuts are often used to support vital building elements such as water pipe brackets and electrical or mechanical installations. They are manufactured with various grooves and edges to reinforce their position when installed.
