5/8-20 Thread Dimensions: Understanding the Specifications
When working with threaded fasteners, understanding the thread dimensions is crucial to ensure proper fitment and functionality. One common thread size used in various applications is the 5/8-20 thread. In this article, we'll delve into the specifications and dimensions of the 5/8-20 thread.
What is the 5/8-20 Thread?
The 5/8-20 thread is a type of thread used in fasteners, such as bolts, screws, and nuts. The thread size is measured in inches, and it consists of two parts: the major diameter and the threads per inch (TPI). In this case, the major diameter is 5/8 inch (0.625 inch), and the threads per inch are 20.
Thread Dimensions
Here are the key dimensions for the 5/8-20 thread:
Major Diameter
The major diameter of the 5/8-20 thread is 0.625 inch (15.88 mm).
Pitch
The pitch of the 5/8-20 thread is 0.050 inch (1.27 mm). This is the distance between two consecutive threads.
Minor Diameter
The minor diameter of the 5/8-20 thread is 0.575 inch (14.61 mm). This is the diameter of the thread at its root.
Thread Length
The thread length of the 5/8-20 thread varies depending on the application and type of fastener. However, a common thread length for this size is around 1-2 inches (25-51 mm).
Thread Class
The thread class for the 5/8-20 thread is typically 2A or 3A, which refers to the thread's tolerance and fitment. Class 2A has a tighter tolerance than Class 3A.
Applications
The 5/8-20 thread is commonly used in various industries, including:
Automotive
