Thread Size - Key Information and Head Dimensions

Selecting the Right Thread Size
Inch fasteners are specified with a size and the number of threads. For example, 1/4"-28 indicates a 1/4" diameter screw with 28 threads per inch.
Metric fasteners are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads.
