Metric Nuts

Metric nuts are threaded fastening components widely used in construction, automotive, machinery, furniture, and various industries in conjunction with threaded elements such as bolts or screws. These nuts are produced in accordance with the metric system of measurements and are identified by a code beginning with “M” (e.g., M8, M10). The number following “M” denotes the diameter of the nut in millimeters, and it is used in conjunction with a corresponding bolt or screw of the same size. When paired with a bolt, metric nuts provide durable and reliable connections.

Metric nuts can be made from various materials, but the most common types are steel, stainless steel, brass, aluminum, and plastic. Steel nuts are often coated with galvanization, stainless coating, or zinc plating to protect them from corrosion. The selection of material and coating type for metric nuts depends on the intended application, strength requirements, environmental conditions, and the materials being fastened.

The most common types of metric nuts include hex nuts, square nuts, blind nuts, flanged nuts, and locknuts. Each nut type is designed specifically for certain applications or assembly processes. For example, locknuts are used to prevent loosening in vibrating environments, while blind nuts are chosen when the open end of the nut is not desired.

Metric nuts offer ease of assembly, high durability, and a wide range of material and coating options. Additionally, they comply with international standards, making them a popular choice for global projects.
