Understanding 5/8-20 Thread: Dimensions, Uses, and Applications
The 5/8-20 thread is a type of thread form used in various industries, including manufacturing, engineering, and construction. In this article, we will delve into the details of the 5/8-20 thread, its dimensions, uses, and applications.
What is a 5/8-20 Thread?
A 5/8-20 thread is a type of thread form characterized by its diameter and threads per inch (TPI). The "5/8" in the name refers to the thread's major diameter, which is 5/8 of an inch or 0.625 inches. The "-20" refers to the thread's TPI, which is 20 threads per inch.
Dimensions
Here are the key dimensions of a 5/8-20 thread:
- Major diameter: 0.625 inches (5/8 inch)
- Minor diameter: 0.575 inches
- Pitch: 0.050 inches
- Threads per inch (TPI): 20
Uses and Applications
