SPENCE INDUSTRIES, INC. - TAPPED HOLE LOCATION GAGES
摘要： Manufactured by Spence Industries, Inc., Precision JO-PLUGS®, are designed to determine Basic Position and Basic Profile of threaded holes. The location and orientation of tapped holes is derived using the pitch cylinder axis of the threaded hole in accordance to ANSI/ASME Y14.5 M – 2015. Significant to the Spence Industries, Inc.
Manufactured by Spence Industries, Inc., Precision JO-PLUGS®, are designed to determine Basic Position and Basic Profile of threaded holes. The location and orientation of tapped holes is derived using the pitch cylinder axis of the threaded hole in accordance to ANSI/ASME Y14.5 M – 2015. Significant to the Spence Industries, Inc. optimal design is the solid thread form with a pitch diameter that is calibrated, front and back, using the universal three-wire method. The JO-PLUG® centerline location plug pitch diameter cylinder is coaxial to the cylindrical “stem” of the gage, establishing a parallel datum axis within which MMC is established. Basic Position and Basic Profile dimensions, which define the orientation and location of the related tolerance zones, are established using CMM or Laser Tracker software. True position of the tapped hole, as well as perpendicularity and projected tolerance zone of the threaded hole is established.
JO-PLUGS® are threaded and inspected in accordance with the International Standard ISO/IEC 17025:2005, which meets the general requirements for the competence of testing and calibration laboratories. This laboratory also meets the requirements of ANSI/NCSL Z540-1-1994 and any additional requirements in the field of calibration.

PRODUCT FEATURES:
- Pitch diameter is coaxial to the cylinder portion of the gage, which projects a greater cylindrical tolerance zone than any other standard center-line locator on the market.
- Pitch diameters are calibrated, (front and back), using the universal three-wire method.
- Standard gaging diameter is .200 (+/-.0001
- Concentricity between gaging diameter and pitch diameter of thread is within .00015 T.I.R.
- Squareness of lapped seating surface to axis is within .0001
