Metric Bolts

Metric bolts are available in a huge range of sizes, shop for great value single bolts or enquire for bulk quantities.

They have a threaded portion that allows them to be screwed into a compatible threaded hole or nut. The most common type of metric bolt thread is the metric coarse thread (M), which has a larger pitch and is typically used for general applications. Another type is the metric fine thread (MF), which has a smaller pitch and is used in applications that require greater precision.

The diameter is expressed in millimeters, representing the major diameter of the thread. For example, an M8 bolt has a major diameter of 8 millimeters.  The most common strength grades are indicated by numbers such as 8.8, 10.9 and 12.9. These numbers represent the bolt's minimum tensile strength in mega pascals (MPa). For instance, an 8.8 bolt has a minimum tensile strength of 800 MPa.

Metric bolts are used in a wide range of applications, including automotive, machinery, construction, and electronics. They are used to secure components, assemble structures, fasten machinery parts, and provide strength and stability in various systems.

Our bolt options include part threaded (Din 931) and full thread (Din 933), also referred to as a setscrew.  Diameters sizes M2, M2.5, M3, M4, M5, M6, M7, M8, M10, M12, M14, M16, M18, M20, M22, M24, M27, M30, M33, M36, M39, M42.  Available in zinc, zinc yellow, stainless steel, brass, and unplated self colour steel.
