Miniature Go No-Go Gages

PRECISION GROUND THREAD PLUG GAGES: These tiny gages are made to very close accuracies on our special CNC controlled grinding equipment in an atmosphere controlled area. Special attention is given to all elements including roundness, taper, lead, angle, pitch diameter and all other dimensions. Prices include mounting in and AGD reversible style handle (usable single and end only) and carefully packaged to protect the threads. You can count on MORRIS Gages for outstanding size control and long life.

SPECIAL GROUND THREAD PLUG GAGES: Threads between 40 and 400 TPI and Metric from .06-.60mm on diameters from .010"-.400" (.25-10mm) can be made to order and computer generated quotations can be made over the telephone or by FAX from descriptions or prints for quantities specified. Truncations and "W" tolerances are available to order. The extra cost for producing reversible gages makes this design not feasible for these tiny sizes.

CALIBRATION SERVICE: This service is available at extra cost to meet strict quality control standards and includes measurement of major diameter, pitch diameter, lead and thread angle with notarized printed certification.

THREAD COMPARATORS: This precise instrument for checking external screw threads has interchangeable segments so that many different thread sizes can be checked with one base unit. The dial indicator output shows where the part is in the tolerance and rotation of the part in the hardened jaws shows up other problems that offer a guide to the procedures needed to correct any problem. They are calibrated for each session with a truncated setting plug and so provide very long service. They are made to order in all sizes in our range and will be quoted on promptly on request. Fixed limit gages are no longer available.
