Product Information

Full details

The SecureFix Direct 12MM x 90MM U Bolt is an essential component for engineers, DIY enthusiasts, and marine technicians who require a robust, reliable solution for securing pipes and tubes. Engineered for high-stress environments, this zinc-plated bolt provides excellent structural integrity for an 80MM nominal pipe bore; however, users should note that while the zinc finish offers corrosion resistance, it may require additional treatment if used in permanently submerged saltwater conditions.

FAQs

What is the internal width of this U bolt?

The internal width (Dimension A) is 90MM.

Does this come with hex nuts?

Yes, each unit includes two matching hex nuts.

Is this bolt stainless steel?

No, this is a zinc-plated steel bolt designed for durability and corrosion resistance in typical environments.

Can I use this on 80MM pipes?

Yes, this bolt is specifically designed to accommodate an 80MM nominal pipe bore.

What are the thread specifications?

The bolt features a 12MM diameter shank, which serves as the primary mounting specification.

Is it suitable for permanent underwater marine use?

While the zinc plating is durable, stainless steel hardware is generally recommended for permanent immersion to prevent long-term corrosion.

Troubleshooting

Nut is difficult to tighten

Check for debris in the threads or ensure the bolt is not cross-threaded. Apply a small amount of lubricant.

Bolt does not fit the pipe

Verify the nominal bore of your pipe. This bolt is specifically sized for an 80MM nominal pipe bore.

Visible signs of rust

Clean the surface with a wire brush and apply a cold-galvanizing spray to restore the protective layer.

Pros and Cons

Pros

  • High-strength 12MM steel construction
  • Includes necessary hex nuts for a complete set
  • Durable zinc-plated finish for extended lifespan
  • Precise dimensions for secure pipe seating
  • Standardized design fits common industrial pipe sizes

Cons

  • Zinc plating may eventually degrade in highly acidic environments
  • Not suitable for extreme high-temperature applications
  • Heavy weight requires stable mounting substrates

Setup, Compatibility & Care

Installation is straightforward but requires correct alignment to prevent cross-threading the nuts. Ensure your mounting surface has pre-drilled holes matching the 90MM width (Dimension A).

  • Compatibility: Designed specifically for an 80MM nominal pipe bore. Ensure your pipe outer diameter matches the inner clearance of the bolt.
  • Care Instructions: To extend the life of the zinc coating, avoid using harsh abrasive cleaners. If the bolt is used in a high-salt environment, periodic inspection for signs of white rust or corrosion is recommended. Applying a light layer of marine-grade grease to the threads can prevent seizing and simplify future removal.
