Metric thread screws, often called fine thread screws, have threads measured in millimeters (mm) based on the distance between each thread, known as the pitch. These screws are commonly used in various industrial applications due to their tight, secure fit and reduced likelihood of loosening over time compared to other types of screws. While most metric screws are used with nuts, some types can be directly screwed into materials. In the future, metric screws will continue to evolve, offering more diverse shapes and sizes to meet specific project needs.

What are Metric Thread Screws?

The metric system for screws measures the distance between threads (pitch) in millimeters, making it straightforward to measure and understand. Simply using a ruler allows you to measure the pitch and quickly determine the spacing of the threads in millimeters.

How to Identify Metric Screw Sizes: Metric screw sizes are typically displayed in this format: 1.) Thread diameter (mm)
2.) Pitch (thread spacing in mm)
3.) Screw length (mm)
