Hughes H90 Non Preferred Rotary Shouldered Connection Thread Plug and Ring Gages

Helpful Tips

  • Before using the gages, make sure they are clean and free of any dirt, rust, or damage that could affect the accuracy of the measurement. You can use a soft cloth or a brush to wipe off any debris from the gages. Do not use any abrasive or corrosive materials that could damage the gage surface or the thread form.
  • To measure the pin end of the connection, use the thread plug gage that matches the size and type of the connection. Insert the gage into the pin end and rotate it gently until it reaches the gauge point, which is the point where the pitch diameter of the gage and the connection are equal. The gage should fit snugly but not too tightly. If the gage is too loose or too tight, it indicates that the connection is out of tolerance and may not perform properly.
  • To measure the box end of the connection, use the thread ring gage that matches the size and type of the connection. Place the gage over the box end and rotate it gently until it reaches the gauge point. The gage should fit snugly but not too tightly. If the gage is too loose or too tight, it indicates that the connection is out of tolerance and may not perform properly.
  • After measuring the connection, inspect the gages for any signs of wear or damage. If the gages are worn or damaged, they should be replaced or recalibrated to ensure accurate measurements. You can also use a thread software tool to verify the dimensions and tolerances of the connection and the gages.
  • Store the gages in a dry and cool place, away from any sources of heat, moisture, or vibration. You can use a protective case or a pouch to keep the gages safe and clean. Do not drop or mishandle the gages as they could lose their accuracy or get damaged.

Hughes H90 Non Preferred Rotary Shouldered Connection - Thread Plug and Ring Gages are tools used to measure the quality and accuracy of the threads on pipes and drill bits used in the oil and gas industry. These gages check the dimensions, pitch, taper, and profile of the H90 thread form which is a 90-degree angle thread with a rounded root and crest.


The H90 thread form is one of the several types of rotary shouldered connections, which are used to join drill pipes, drill collars, and other components of the drill string. Rotary shouldered connections are characterized by having a pin and a box end, which are screwed together to form a tight seal and transmit torque and axial load. The H90 thread form is considered a non preferred connection so it is not widely used or recommended by the American Petroleum Institute (API) which is the leading standard-setting organization for the oil and gas industry.
