Typically, if an internal threaded part is cut too large (too much material removed during threading), it ends up being rejected or scrapped. Because API RSC threads are tapered, moving the shoulder back makes the “over-sized” thread essentially “smaller.” When cutting/inspecting an internal API box rotary shouldered connection, it is not necessary to scrap the […]
Typically, if an external threaded part is cut too small, it ends up being rejected or scrapped. Because API RSC threads are tapered, moving the shoulder back makes the “under-sized” thread essentially “larger”. When cutting/inspecting an external API pin rotary shouldered connection, it is not necessary to scrap the part if the thread is measured […]

For many years, Gagemaker has shared a longstanding relationship with Mitutoyo by exclusively using their indicators on all […]
Not all threads are cut in the same direction. Left hand and right hand threads can be misidentified at first sight. A simple visual check can help avoid any costly missteps. While standing at the face of the connection, look down on the thread. If the thread groove appears to rise up from the bottom […]
Get Efficient! Industries across the globe rely on the efficiency of their manufacturing processes to create high quality parts and stay profitable. There is no longer room for broken machines, unmotivated employees, or disorganized processes – all which ultimately result in low profits and failing parts. Manufacturing efficiency is critical and it can always be […]
Inspecting the minor diameter on rotors can be done easily with Gagemaker. For measuring the minor diameter, you have two options based on the number of lobes/peaks: Even number of lobes (2, 4, etc.) The “valley to valley” measurement can be achieved using an Minor MIC gage (MM-06). The contact balls ride in the valleys […]
Per API 7-2, the shoulder contact face is required to be plane and square with the thread axis within 0.002″. You can detect a severely out-of square shoulder by sweeping a thread profile template up the thread’s helix until it butts up against the face of the shoulder. A visible or measured gap in excess […]
When setting functional roll gages to zero, it’s smart practice to record the revolution count as seen on the small dial of the indicator. Place a small piece of masking tape on the metal plate beneath the indicator, and record the rev count. This ensures you don’t machine your part one or more rev counts […]
Thread inspection using thread rolls make a lot of sense when you have a better understanding of how it all works. Both the PG-6000 and RG-7000 gages use 2 thread rolls that are precision ground to seat into the thread form and contact the thread at the pitch line.The gages are preset and zeroed to […]
