Vermont Gage Steel Go Plug Gage Tolerance Class ZZ 0.9895 Gage Diameter for $15.26

Description: Vermont Gage Steel Go Plug Gage Tolerance Class ZZ 0.9895 Gage Diameter The Vermont Gage steel go (+) plug gage is a class ZZ inch gage for calibrating measuring equipment and gage parts. A certificate of accuracy traceable to NIST is available for each gage and each pin is marked with its size and direction of tolerance in sizes over .060”. Each gage is sealed in a volatile corrosion inhibitor (VCI) bag and packaged with a rust preventative. All gages measure 2” long are within .00001” round (per ASME B89.1.5) and have at least a 10-microinch finish for a smooth finish. This gage is made of tool steel 60/62 Rc (cold stabilized) for durability and is available with either a steel or black guard finish (to inhibit corrosion and for indicating wear). Sizes are available from .0040” to 1.0005” (increments of .001”) with a tolerance of +.0002” for longer wear. Plug gages are precision ground cylindrical steel plugs used to measure the diameter and depth of drilled or machined holes. They are available in different classes based on acceptable tolerance (allowed deviation from the stated size). Standard tolerances and classes for cylindrical gages up to .825” are as follows: Class XX (.00002 or .0005 mm) Class X (.00004 or .0010 mm) Class Y (.00007 or .0018 mm) Class Z (.0001 or .0025mm) and Class ZZ (.0002 or .0050 mm). For gages with a wider diameter tolerance gradually increases for each class. Since 1968 Vermont Precision Tools Inc. (VPT) has been manufacturing a variety of precision round and ground pins perforators and special punches. Vermont Gage was formed in 1980 and manufactures a wide range of fixed limit gages. Located in Swanton Vermont and Franklin Kentucky Vermont Gage manufactures 98% of the products they sell and is ISO 9001:2000 and ISO 17025 quality certified. - Supplied with a certificate of accuracy traceable to National Institute of Standards and Technology (NIST) - Go (+) gage for measuring the lower limit of a hole - Available in a range of sizes from .0040” to 1.0005” - Made from tool steel 60/64 Rockwell c scale (Rc) cold stabilized for durability - Class ZZ (tolerance of .0002”) for longer wear - - -
