How big is a pitch circle in a bolt?
Bolt Pattern/Pitch Circle Diameter (PCD) The center of every bolt/lug lies on the circumference of a circle that they create. PCD is usually measured in millimeters (mm). For example, the 5×114.3 (or 5×4.5 in inches) PCD that our 3G TLs use means that there are 5 lug holes, with a pitch circle diameter of 114.3mm or 4.5in.
What do you need to know about thread pitch?
The thread pitch is the measurement of either threads per inch for non-metric studs or the distance in millimeters between the threads for metric applications. This tool will help identify the proper thread pitch that was on the vehicle from the factory. If the vehicle has been modified, you will need to verify the thread pitch.
How is the thread pitch of a fastener measured?
The thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm. In general smaller fasteners have finer thread so they have lower thread pitch.
How big of a thread do I need for a wheel lock?
The thread size or thread diameter is the measurement taken across the outside diameter of your wheel stud threads measured in either standard (7/16″, 1/2″, etc.) or metric (12mm, 14mm, etc.) dimensions. The most common thread sizes are 10mm, 12mm, 14mm, 7/16″, 1/2″, 9/16″, 5/8″.
Where do I find thread pitch on my wheel?
You can usually find your factory stud size in your vehicle owner’s manual. What is Thread Pitch? The thread pitch is the measurement of threads per inch for US standard wheel studs or the distance in millimeters between the threads for metric applications.
How big are the threads on a wheel?
The thread size or thread diameter is the measurement taken across the outside diameter of your wheel stud threads measured in either standard (7/16″, 1/2″, etc.) or metric (12mm, 14mm, etc.) dimensions.
What is the thread pitch on a lug?
US lugs specify threads per inch (TPI), commonly called thread count, so 20 would represent 20 threads per inch. While metric lugs specify a thread pitch which is the distance between the threads. Therefore, a 1.5 pitch would have 1.5 millimeters between each thread.
What is the pitch of a metric fastener?
Metric fasteners are specified with a thread pitch instead of a thread count. The thread pitch is the distance between threads expressed in millimeters (measured along the length of the fastener). For example a thread pitch of 1.5 means that the distance between one thread and the next is 1.5mm.
