Product Code: Gagemaker LG-5003-J
Gagemaker LG-5003-J, 3-point external/internal lead gage, ½” – 4” (0 mm – 101.6 mm)Thread Length
The LG-6001 and the LG-6002 use a two-point system to inspect thread lead for straight and tapered threads. The LG-6002 inspects both external and internal threads, while the LG-6001 inspects external threads. The two point system allows for a sweeping action to obtain the measurement. Both gages are available with higher resolution indicators.
Contact points can be easily changed to allow the gage to be used on a variety of thread forms. Each gage comes with a default set of contact points, but customer may specify another set.The LG-5003 uses the three-point system to inspect internal and external thread lead. 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.
Before inspecting parts, the lead gage must be preset to a nominal predetermined dimension using a lead gage setting standard. Lead standards are available for both straight and tapered threads. Our setting standards are manufactured according to ANSI and API specifications, respectively
