Threaded Rods & Studs

Threaded rods or studs are a type of fixing that’s commonly used in various construction, manufacturing and automotive industry jobs, as well as in a wide range of plumbing and marine applications.Their main purpose is to fasten wood, stone or metal surfaces and components securely together. In this capacity, a threaded rod/stud is often inserted into wood or concrete elements and used to help stabilise structures.They’re typically sold in a selection of different materials, lengths and diameters, and our range of threaded rods is available in numerous common thread sizes/gauges.What should you look for when buying threaded rods and studs?Material: Most threaded rods are generally constructed from metals such as mild steel or stainless steel, although they’re also widely available in other types of materials, including both brass and nylon.Thread sizes and lengths: Threaded rods can be bought as either fully threaded fasteners (with the threading running the entire length of the shaft), also known as fully threaded stud bolts, or with unequal thread lengths.Unequal thread length means the threading is divided into two uneven sections along the shaft, with an unthreaded portion somewhere in the middleUnequal threaded rod is sometimes known as a tap-end stud bolt; the shorter threaded portion fastens into a tapped hole, while the longer threaded section takes a fastener such as a nut and washerStandard metric screw threading on rods and studs is typically denoted by the letter M on the packaging/manufacturer specifications, and will then be follow.ed by the diameter of the rod (given in millimetres) – for example M2, M4, M6, M8, M20, and so onThread pattern: Threaded rods and studs can either be sold in a right-hand thread pattern, or in a left-hand pattern.Right-hand threads require a clockwise rotation in order to tighten the threaded rod to a material or fastener – this is very much the standard configurationLeft-hand thread patterns are less common, but sometimes required for specialised uses or environments in which vibration movement may cause a right-hand threaded rod to work loose over time
