Threaded Rod

What is threaded rod (all thread)?

A threaded rod (or all thread) is a metal rod threaded along its entire length, allowing secure fastening with nuts and washers in applications where standard bolts are not long enough. It provides a simple yet highly adaptable fastening solution for connecting or stabilising materials including wood, metal, and concrete.

Typical applications for threaded rod

Threaded rods and threaded bars are widely used across construction, engineering, manufacturing, plumbing, and maintenance applications. They provide strength and stability in structural frameworks, suspended installations, machinery, bracing systems, and general fastening applications.

The choice of material depends on the installation environment. Corrosion-resistant stainless steel threaded rods are commonly specified for outdoor, marine, and high-humidity environments, while carbon steel grades are suitable for many general engineering and industrial applications.

What types of threaded rod are available?

Fastenright supplies threaded rods in multiple configurations, including:

• Fully threaded rods
• Partially threaded rods 
• Right-hand threaded bars
• Left-hand threaded bars
• ACME thread forms
• Trapezoidal thread forms

Custom thread styles, lengths, and internally threaded rod options are also available to order. 

Thread sizes and available dimensions

Standard threaded rods are available in a wide range of diameters and are stocked in standard lengths of 1 metre, 2 metres, and 3 metres, with alternative lengths available on request.

Bars can also be cut to size to suit specific installation requirements.

What materials and finishes are offered?

Our threaded rods are available in a wide range of materials, including:

• Steel grades 4.8, 5.8, 8.8, 10.9, and 12.9
• A2 stainless steel
• A4 stainless steel
• A5 stainless steel
• A8 stainless steel
• Brass
• Aluminium
• Nylon
• Titanium

For demanding applications, exotic materials including Duplex Stainless Steel, Inconel, Monel, and Hastelloy are also available.

Available finishes include:

• Zinc plated
• Galvanised
• Powder coated
• Stayblack

Selecting the appropriate material and finish helps ensure the threaded rod performs reliably within its operating environment. Stainless steel grades are commonly selected where corrosion resistance is required, while high-tensile steel grades are often chosen for structural and heavy-duty engineering applications.

How to use threaded rod

To fasten two materials together, pass the threaded rod through pre-drilled holes in the materials. Fit a washer onto each exposed end of the rod, followed by a nut, before tightening both nuts to create a secure connection.

How to measure threaded rod

To measure threaded rod, first measure the diameter across the widest part of the thread. To determine the overall length, measure from one flat end of the rod to the other using a ruler or tape measure. Threaded rod measurements are typically specified in millimetres.

Can our threaded rods be supplied in custom lengths?

Yes. Alongside standard stock, Fastenright can supply threaded rod in custom lengths, materials, finishes, and thread forms to suit specialist applications.

With over 30 types of threaded rod and threaded bar available, we also manufacture bespoke products to customer drawings and specifications.
