Automotive Terminology: Understanding Bolts and Nuts

Bolts and Nuts Naming Convention in Automotive Terminology

In automotive terminology, bolts and nuts are typically named based on their size, thread type, and specific application.

Bolts are commonly referred to by their diameter, length, and thread pitch. The diameter is measured across the shank of the bolt, while the length refers to the distance from the bolt head to the tip. The thread pitch indicates the number of threads per inch or millimeter.

Nuts are often identified by their corresponding bolt size and thread type. For example, a nut that fits a 10mm diameter bolt with a 1.5mm thread pitch would be referred to as a "10mm x 1.5" nut.
