Metric Trust Wire Nut

A metric thread is a type of thread standard, also known as a metric thread. The biggest difference from English threads is that pitch is measured in millimeters. Metric threads come in several types, including regular threads (with a profile angle of 60°), trapezoidal threads (with a tooth angle of 30°), serrated threads (with a tooth angle of 33°), and square tooth threads. Metric threads are represented by pitch, while American and British threads are represented by the number of threads per inch. This is their biggest difference.

Metric threads have a 60-degree equilateral profile, British threads have an isosceles 55-degree profile, and American threads have a 60-degree profile. Metric threads are measured in metric units, while American and British threads are measured in imperial units. Metric threads are widely used, especially in European and Asian countries, as a standard thread for connecting mechanical parts.

They include two types: coarse metric threads and fine metric threads, with coarse threads suitable for high-load connections and fine threads suitable for low-load connections. The use of metric threads helps standardize production and design, reduce production costs, and improve production efficiency.
