Gagemaker Thread Lead Gauge

The lead gauge inspects thread lead using contact points that seat in the threads of a part. Thread lead is the distance between threads, measured on a plane parallel to the centerline of the threaded part. The pitch of the thread determines the diameter of the contact points required for taking measurements. API specification 7-2 requires thread inspection.

Product Description

Point system allows for a sweeping action to obtain the measurement. Both gauges are available with higher resolution indicators.

The LG-5003 uses the three-point system to inspect internal and external thread lead. Two fixed contact points at the rear of the gauge and one moveable contact point at the front of the gauge provide complete stability when taking thread lead measurements. This unique design does not require sweeping to obtain measurements.

Contact points can be easily changed to allow the gauge to be used on a variety of thread forms. Each gauge comes with a default set of contact points, but customers may specify another set.

Before inspecting parts, the lead gauge must be preset to a nominal predetermined dimension using a lead gauge setting standard. Lead standards are available for both straight and tapered threads. Our setting standards are manufactured according to ANSI and API specifications, respectively.
