Threaded Rod (Booker Rod / Allthread Rod)
Threaded rod, also known as Booker Rod or Allthread Rod, is widely used in mechanical, electrical and plumbing (MEP) installations for suspension, bracing and structural support assemblies. It provides continuous threading along its length, allowing adjustable fixing for cable trays, pipework, ducting and strut channel systems.

Ozstrut supplies threaded rod in multiple finishes to suit different environmental and corrosion conditions across commercial, industrial and infrastructure projects in Australia.
Available Finishes
Threaded Rod – Zinc Plated
Zinc plated threaded rod is suitable for most indoor commercial applications where corrosion exposure is minimal. It is commonly used for internal service suspension and general construction fixing.
Threaded Rod – Hot Dip Galvanised (HDG)
HDG threaded rod provides increased corrosion resistance and is recommended for outdoor installations or environments exposed to moisture and weather conditions.
Threaded Rod – Stainless Steel 304
Stainless 304 threaded rod offers strong corrosion resistance for general industrial and coastal-adjacent applications where durability is required.
Threaded Rod – Stainless Steel 316
Stainless 316 threaded rod is designed for highly corrosive environments including coastal and marine applications where superior corrosion resistance is essential.
Common Applications
- Suspension of cable trays and containment systems
- Pipework and plumbing supports
- HVAC ducting suspension
- Fire sprinkler system hangers
- Trapeze and strut channel support assemblies
Choosing the Right Threaded Rod
When selecting threaded rod, consider:
- Rod diameter (M10, M12, M16 and others as specified)
- Required load capacity
- Installation environment and corrosion exposure
- Compatibility with nuts, washers and channel fittings
For engineered installations, always follow project specifications and relevant Australian standards.
Compatibility with Support Systems
Threaded rod is commonly used together with:
- Beam clamps for steel beam suspension
- Slotted angle for bracing and framing
- Wedge nuts for channel connections
- Perforated cable tray for cable support assemblies
These components form complete suspension and support systems for building services installations.
Frequently Asked Questions
What is threaded rod used for?
Threaded rod is used for suspension and support assemblies including cable trays, pipework and HVAC systems. It allows adjustable installation due to its continuous thread.
Is threaded rod the same as Booker Rod?
Yes. Booker Rod and Allthread Rod are common industry terms used to describe fully threaded rod products.
What is the difference between Zinc, HDG and Stainless threaded rod?
Zinc plated is suitable for indoor use. HDG provides increased corrosion resistance for outdoor environments. Stainless 304 and 316 offer superior corrosion resistance, with 316 suited to marine and highly corrosive environments.
Which stainless steel grade should I choose?
Stainless 304 is suitable for most industrial environments. Stainless 316 is recommended for coastal or highly corrosive applications.
