Abstract
A thread ring gauge holder that is used with a thread ring gauge to eliminate the variance in applied torque from different people using the thread ring gauge. This device allows the thread ring gauge to be protected from an excessive amount of torque and from a premature false reading from applying too little torque from a wide variety of users. The device can be used together with a variety of thread ring gauges and is made up of a ring gauge adapter, a ratchet drive, a ratchet gear, a protective housing that accommodates a ball plunger and a pawl device and a snap ring to hold the thread ring gauge holder together in place with the thread ring gauge. The ball plunger and pawl act as a torque setting device to control the amount of torque that is applied to the thread ring gauge, thereby insuring repeatability and consistency.
