FAQ

What is the difference between coarse and fine thread size for bolts?

Coarse thread size has fewer threads per inch compared to fine thread size, providing a quicker assembly but with less holding strength.

How is bolt thread size measured?

Bolt thread size is measured by two main factors - the diameter of the bolt and the pitch of the threads, which indicates the distance between each thread.

What are common thread sizes for bolts used in automotive applications?

Common thread sizes for bolts used in automotive applications include M6, M8, M10, and M12, with variations in thread pitch and length.

How does the thread size of a bolt impact its application?

The thread size of a bolt determines the compatibility with corresponding nuts, as well as the load-bearing capacity and overall strength of the connection.

Why is it important to use the correct bolt thread size for a specific application?

Using the correct bolt thread size ensures a secure and reliable connection, minimizing the risk of loosening, failure, or damage due to mismatched components.
