i Technical information 7.2.2 Gauges R, Rc/Rp Gauge No. 1 Taper full form threaded plug gauge. This gauge is a 1:16 taper full form threaded plug gauge and is suitable for checking the major diameter (D) and pitch diameter (D2) at the gauge plane of internal parallel (Rp) threads and internal taper (Rc) threads. Gauge No. 2 Taper full form threaded plug gauge with relief. This gauge is a 1:16 taper full form threaded plug gauge with relief of threads and is suitable for checking the major diameter (D) and pitch diameter (D2) at the gauge plane, and the accomodation 1lenght of inernal parallel (Rp) threads and internal taper (Rc) threads. 1Accomodation lenght: distance from the face of an internally threaded workpiece to the first obstruction which the externally threaded workpiece will encounter on assembly. Gauge No. 3 Parallel full form threaded ring gauge. This gauge is parallel full form threaded ring gauge and is suitable for checking the minor diameter (d1) and pitch diameter (d2) at the gauge plane of taper external (R) threads. Gauge No. 4 Taper plane ring gauge. This gauge is a 1:16 taper plain ring gauge and is suitable for checking the major diameter (d) and the related useful thread lenght on taper external (R) threads. Gauge No. 5 Taper modified thread form check plug gauge This check plug gauge is used to check the dimensions of the parallel threaded ring gauge (gauge No. 3) when manufacturing the ring gauge and for checking the ring gauge for wear. 12 304
