An M12 x 1.25 tap is a precision tool used to cut or repair internal threads in metals, plastics, or other machinable materials. The “M12” indicates a metric thread with a 12 mm diameter, while “1.25” specifies the thread pitch, meaning the distance between each thread is 1.25 mm. Typically made from high-speed steel (HSS) or HSSE for durability and heat resistance, this tap provides reliable, long-lasting performance. It is widely used in metalworking, automotive, and industrial applications where strong, accurate internal threads are required for bolts, screws, and fasteners, ensuring secure and precise assembly.
