Collection: Channel Nuts

Stainless steel channel nuts are specialist fixings designed for use with strut channel systems such as Unistrut. They slide into the channel profile to provide a strong, adjustable threaded fixing point without the need for drilling or welding. Also known as channel spring nuts or Unistrut channel nuts, they are widely used across electrical, mechanical and construction installations where corrosion resistance and flexibility are required.

Fixabolt supplies stainless steel channel nuts in practical trade formats, including plain and spring-loaded options, suitable for indoor, outdoor and corrosive environments.

Why choose stainless steel channel nuts from Fixabolt

  • Corrosion-resistant stainless steel for long service life
  • Compatible with standard Unistrut and similar channel systems
  • Available as plain channel nuts or sprung versions
  • Metric thread sizes to suit common fixing requirements
  • Supplied for trade use with consistent quality and sizing

Spring channel nuts are particularly useful where hands-free positioning is needed, such as overhead installations or confined spaces.

What channel nuts are used for?

Channel nuts are used to create threaded fixing points inside strut channel sections.

Typical applications include:

  • Supporting pipework, cable tray and conduit systems
  • Fixing brackets, frames and support rails
  • HVAC and mechanical service installations
  • Electrical containment and plant mounting
  • Modular framing systems in industrial or commercial settings

Because the nut can be positioned anywhere along the channel, systems can be adjusted or expanded without dismantling the structure.

Materials and standards

Stainless steel channel nuts are typically manufactured in:

A4 (316) stainless steel – recommended for marine, coastal or chemically aggressive environments

Channel nuts are designed to fit standard strut channel profiles commonly used across the UK.

How to choose the right channel nut

When selecting stainless steel channel nuts, consider the following:

Thread size: Match the nut to your bolt size. Common options include M6, M8, M10 and M12.

Plain or spring-loaded: Plain channel nuts are simple and robust. Spring channel nuts hold themselves in place inside the channel, making installation faster and easier.

Spring length: Short spring nuts suit standard channel depths. Long spring channel nuts are helpful in deeper channels or vertical runs.

Material grade: Use A4 where high corrosion resistance is required.

This range includes:

Plain stainless steel channel nuts

Short spring channel nuts

Long spring channel nuts

Multiple metric thread sizes

Use size-specific product pages to select the correct thread and format for your installation.

FAQs

What are stainless steel channel nuts used for?

They are used to create threaded fixing points inside strut channels, allowing brackets, clamps and fittings to be securely fixed without drilling or welding.

What is the difference between plain and spring channel nuts?

Plain channel nuts are positioned using the bolt during installation. Spring channel nuts include an integrated spring that holds the nut in place inside the channel, making installation quicker and easier, especially overhead.

Which stainless steel grade should I choose?

A2 stainless steel is suitable for general indoor use but A4 stainless steel offers higher corrosion resistance and is recommended for outdoor, marine or harsh environments.
