The lead gage inspects both internal and external thread lead using contact points that seat in the threads of the part. Thread lead is the distance between threads, measured on a plane parallel to the threaded part. The pitch of the thread determines the diameter of the contact points required for taking measurements.
The LG-5002 uses a two-point system to inspect thread lead for ACME, Stub ACME, UN, or API threads. The two points allow for a sweeping action to obtain the measurement.The LG-5003 uses the three-point system to inspect thread lead for ACME, Stub ACME, UN Threads, or API Thread. Two fixed contact points at the rear of the gage and one moveable contact point at the front of the gage provide complete stability when taking thread lead measurements. This unique design does not require sweeping to obtain measurements. Plus contact points can be easily changed to allow the gage to be used on a variety of thread forms.
Before inspecting parts, the lead gage must be preset to a nominal predetermined dimension using a lead gage setting standard. These setting standards are manufactured according to ANSI and API specifications. Lead standards are available for ACME, Stub ACME, UN and API threads.

Internal & External Taper Gages
The Internal & External taper gages measure variation in connection taper. Taper gages are shipped with .072" diameter contact points as standard. However, each set of contact point is interchangeable to allow measuring different thread forms. COntact point diameters are manufactured to tolerances of +.0002". The pitch of the thread and type of the thread form determine the diameter of the contact points required for taking measurements.Feature
- Internal Taper Gages use for inspects external threads for API thread forms ranging from 1 ½” – 24”.
- External Taper Gages use for inspect external threads for API thread forms ranging from 0” – 24”.
- Uses interchangeable contact points to allow inspection on a variety of thread forms.
- Requires no setting master.
