# How Do I Measure a Bolt Correctly?

When measuring a bolt, you need to determine the diameter (D), the threads per inch (TPI), and the length under the head (L)?For example, a ½” bolt with 13 threads per inch and 4” long would be written as ½-13 X 4. This ensures you get the right fastener for your job..
# What Do the Markings on the Head of a Bolt Mean?
