Types of Threaded Rods

The types below cover the threaded rod formats and material options most commonly specified for construction, engineering and industrial assembly applications in NZ.

Threaded Bar

A threaded bar is a long, straight, round bar manufactured by cold-forming from low-carbon or stainless steel. Its surface shot blasted, pickled and electroplated with zinc passivation and it is used for general engineering purposes and for manufacturing screws, nuts, bolts and other fasteners. Threaded bars are available in many different grades of steel that vary in strength and hardness, and these properties determine the suitability of the bar for a specific application.

All Thread and Threaded Studs

All-thread rods and threaded stud rods are fully threaded fasteners with continuous machine threads running the entire length. They bolt components together with nuts at both ends, or thread through tapped intermediate points, making them well suited to anchoring, machinery assembly and any joint that needs a versatile fastener cut to length on site. Our guide to thread locks covers the compounds used to secure threaded rod stud joints against vibration.

Fully vs Partially Threaded Rods

Fully threaded rods carry threads across their entire length, giving flexibility for on-site cutting and adjustment. A partially threaded rod threads at each end and leaves the mid-section smooth, providing better shear strength where the joint sits across the smooth section rather than through the thread.

Materials

Threaded rods are stocked across a range of materials matched to the working environment. Zinc-plated steel threaded rods are the general-purpose default; stainless steel resists corrosion in outdoor, marine and food-contact applications while nylon and aluminium threaded rod formats suit light-duty, electrically insulating or low-weight installations. High strength threaded rod grades in alloy or heat-treated carbon steel also deliver the tensile capacity needed for structural anchor and heavy machinery mounting applications.

Industrial Applications of Threaded Rods

Threaded rods are specified across construction, industrial manufacturing and food processing in NZ. In each of these sectors, a versatile fastener with continuous or partial threading delivers the joint strength, adjustment or serviceability the application needs. For guidance on lubrication and maintenance of the machinery and threaded joints in these environments, refer to our machinery lubricants guide.

• Automotive: Threaded rods are used in cars to secure the body panels together. They are also used in the manufacturing process to align parts during assembly. Heavy-duty threaded rod stud fasteners appear in engine mounts, drivetrain assembly and chassis reinforcement across NZ vehicle manufacturing and repair workshops.
• Building: Threaded rods are often used in construction projects as part of scaffolding and wind turbines. They also carry suspended services such as cable trays, pipework and HVAC ducting from the structural ceiling on high-strength threaded rod hangers. Fully threaded rod is the typical specification in these hanging installations because it allows the length to be cut on site to suit the drop.
• Food & Beverage: Threaded rods are used in the production process at breweries, wineries, dairy factories, and other food and beverage producers worldwide. Stainless steel is the standard specification in food-contact zones for its hygiene and corrosion resistance, and threaded studs support tank mounts, conveyor supports and equipment frames throughout the plant.

Across all three sectors, matching the material (steel, stainless, nylon or aluminium threaded rod) and thread coverage (fully or partially threaded) to the working environment is crucial.
