Allthread Connectors

Allthread Connectors, also commonly referred to as coupling nuts or barrel nuts, are used to join two lengths of threaded rod together to create longer continuous runs. Widely used in mechanical, electrical and construction installations, they provide a strong and reliable connection within suspended and structural support systems.

 
Manufactured for strength and durability, they are suitable for a wide range of load-bearing applications where extended threaded rod lengths are required.

Key Features

• Designed to join two lengths of threaded rod securely 
• Also known as coupling nuts or barrel nuts 
• Strong load-bearing connection for structural applications 
• Compatible with standard metric threaded rod 
• Suitable for suspended and fixed support systems 
• Available in corrosion-resistant finishes

Product Description

Allthread Connectors are precision-engineered fastening components used to join two sections of threaded rod in a straight, secure alignment. Internally threaded along their full length, they allow rods to be screwed in from both ends, creating a continuous threaded connection capable of transmitting load along the full assembly.

These connectors are widely used in suspension systems for pipework, cable containment, ducting and structural bracing, where standard rod lengths are insufficient. They are also commonly used in construction and fabrication environments to extend threaded assemblies without compromising strength or alignment.

 
Manufactured from high-strength steel, they provide dependable mechanical performance under load and are designed to maintain a secure connection even in vibration-prone environments. Their simple but effective design makes them an essential component in channel support and threaded rod systems.

 
Available in M10, M12, M16 and M20 sizes, with finishes in BZP (Bright Zinc Plated) for general indoor use and HDG (Hot Dip Galvanised) for improved corrosion resistance in external or demanding environments.

Applications

Ideal for use in channel support systems, suspended services, structural frameworks and general construction applications where extended lengths of threaded rod are required for pipework, cable trays, HVAC and M&E installations.
