Threaded rod, also called stud bar, all-thread or threaded bar, is threaded along its full length and cut to the length you need. This guide covers the common metric sizes, materials and uses.

A threaded rod is a steel bar with a continuous external thread along its whole length. Unlike a bolt it has no head, so it is used with nuts and washers on both ends, or screwed into an anchor, coupling nut or tapped hole. Because it can be cut to any length, it is the standard choice for long fixings, suspensions and anchoring.
In India, metric coarse threads (ISO) are the most common. The size number is the nominal outside diameter in millimetres.
Fine-pitch threads (for example M10 × 1.25) and inch threads such as BSW also exist, especially on older machinery. Always match the nut to the rod thread.
Threaded rods are commonly supplied in lengths such as 1 m, 2 m and 3 m and then cut to size on site. DIN 975 is a widely referenced standard for metric threaded rods.
Hot-dip galvanised rods have a thicker zinc layer on the thread, so use nuts made for galvanised threads.
• Suspending pipes, cable trays and ducts from slabs or beams, with anchors
• Supporting slotted channel frames and brackets
• Anchoring machinery, base plates and structures
• Clamping fixtures, jigs and assemblies
• Extending fixings with coupling nuts
• Measure the outside diameter with a vernier caliper: about 10 mm means M10
• Check the pitch with a thread gauge, or measure 10 mm along the rod and count the threads
• Note the material and finish (black, zinc, galvanised, stainless)
• Measure the length you need, or the number of pieces and cut length
Hex nuts, washers, coupling nuts, anchor fasteners and channel nuts are commonly ordered with threaded rods. See our fasteners page.
