Thread Pitch Gauges

What are thread pitch gauges?
A thread pitch gauge is used to measure the pitch or lead of a screw head.
They are designed to determine the gradient for external and internal threads. Useful for checking tool angle while cutting threads in metal turning lathes.
This tool is not used as a precision measuring instrument, rather it allows the user to determine the profile of the given thread and quickly categorise the thread by shape and pitch. This device also saves time, in that it removes the need for the user to measure and calculate the thread pitch of the threaded item.
How to use a thread pitch gauge
To use a thread gauge, first match the type of thread to the gauge. For example, attempting to measure metric threads with an imperial gauge will not return accurate results. To determine the correct gauge, a process of trial and error may be needed if the screw is of unknown origin.
Once the correct gauge is determined, the user should extend one of the leaves of the tool and press it against the threaded portion of a screw. If the teeth (cut into the leaf) match the spacing of the thread, then the user can read off the thread pitch stamped into the leaf. If the fit is not good, the user should try a different leaf.
• Never force a gauge into or on a part being checked
• Handle gauges as you would any precision tool
• Misuse or mishandling can result in nicks or other deformities which can destroy the integrity of the gauge
• Store gauges in a secure location, preferably in individual compartments or containers
• Gauges should be dipped in an oil-wax based seal or coated with a rust preventive prior to storing
