Threaded Jo-Plugs

Precision JO-PLUGS® are threaded plugs with a concentric stem. Precision JO-PLUGS® allow a CMM machine to measure the position of a threaded hole to the actual pitch diameter. This is a very effective way to accomplish this task.

CMMshop.ca offers a wide range of standard Unified series and Metric series threaded position JO-PLUGS®. We can also provide any special threaded JO-PLUG® configuration that you need upon request. Most standard sizes are in stock for next day delivery.

Pipe thread, Heli-Coil true position Precision JO-PLUGS®, and any other special sizes are available upon request.
