Description M6 x 1  —  EDP: SPE6001MT Thread Size M6 x 1 EDP Number SPE6001MT Tolerance Class 6H Pitch 1 mm Major Diameter 6 mm Go Basic Pitch Diameter (mm) 5.35 Calibration ISO 17025:2017 Accredited, NIST Traceable Certificate of Conformance Included at no charge Origin Made in USA — Warren, MI Metric Series pitch diameters are “Go Basic,” suitable for Class 6H Standard Shaft Length: .625″ Standard Shaft Diameter: .200″ ( /- .0001″) (5mm metric /-.0025) C of C traceable to NIST and ISO/IEC 17025:2018 and ANSI/NCSL Z540-1-1994 Accreditation at no charge Precision JO-PLUGS® are designed to determine Basic Position and Basic Profile of threaded holes.  Thread grinding and inspection are performed in an ISO-17025:2017 A2LA Accredited facility, Certification #3692.01. This laboratory meets the requirements of ANSI/NCSL Z 540-1-1994 and ANSI/ASME B1.12-1991 and B1.16M-1984. A pitch diameter is a constant number and Precision JO-PLUGS® provide a calibrated pitch cylinder parallel to internal threads. The location and orientation of tapped holes is derived using the pitch cylinder axis of the threaded hole in accordance to ANSE/ASME Y14.5 2018.
