Plug Gages

National Institute of Standards and Technology Calibrated Masters Certification of accuracy and traceability to the National Institute of Standards and Technology is included with every Deltronic gaging product.
 

This no-charge feature has its foundation in masters calibrated for us by by the National Institute of Standards and Technology. In order to translate the Institute measurements to the production of an accurate gaging product, there are three essential elements required. First, knowledgeable and experienced personnel; second, a suitable gage making/measuring environment; third, production and measuring equipment with inherent accuracy and resolution to satisfy the millionths requirements of our end products. Through many years of gage-making experience Deltronic has evolved a mix of these essential elements to provide our customers with the maximum in consistent product quality at minimum cost.

Class X Stock Gages

Exclusive Patented Features

Deltronic has originated so many unique and valuable features in its plug gages that they have been granted patent number 2,715,281 by the United States Patent Office.

Single Tolerance

Every Class X Deltronic gage is made to a single tolerance, plus .000,040", minus nothing, with Certification of Accuracy traceable to the National Bureau of Standards.

Size on Each Gage

This self identifying feature eliminates time spent in manually checking and re-checking gage sizes reducing the possibility of error.

Exclusive Relief Handle

Enanbles use without the encumbrance of handles for greater versatility of applications. May also be used with handles when desired.

Extra Length

Length varies with diameter from 1 7/8" to 3 1/2" to provide more useable gage surface.

Absolute Concentricity

This concentricity of ends, plus extra length, is invaluable for layout, hole spacing measurement.

Precision Lapped

Each gage is lapped to approximately one microinch finish that creates a mirror-like surface with additional resistance to wear.

Hardened and Cold Stabilized

Heat treated to a hardness of Rockwell "C" 62-64, and Cold Stabilized to minimum size and form variations throughout the exceptionally long life potential built into each Deltronic gage.

Tiny X Gages with Insul-Grip

The insulator grip supplied free with Deltronic gage sizes .0070" thru .0589" is an original Deltronic concept that provides new convenience in handling and control of small diameters. The Insul-Grip prevents transfer of hand heat, acids and moisture in handling, and provides instant, size-marked identification. The Insul-Grip can be moved to any point on the gage or easily removed and replaced for such uses as gear or thread wires or in AGD handles. Tiny X gages maintain the same Deltronic plus 40 millionths, minus nothing, tolerance and are precision lapped, hardened and cold stabilized, and extra long for more useable gage surface.
