Deltronic Class X Plus Hardened Steel Gauge Pins .1081″ – .3872″ / 2.7450mm – 10.0350mm

Deltronic Class X Plus Hardened Steel Gauge Pins .1081″ – .3872″ / 2.7450mm – 10.0350mm

The Deltronic Class X Plus Hardened Steel Gauge Pins .1081″ – .3872″ / 2.7450mm – 10.0350mm are precision-engineered inspection tools built to meet the rigorous standards of Class X tolerances. These Hardened Steel Gauge Pins are ideal for dimensional verification, tooling setups, and quality assurance in demanding manufacturing and metrology environments. Each gage in this range is manufactured with exacting attention to tolerance and finish, ensuring consistent and reliable performance over extended periods of use.

Designed for accuracy and ease of use, these pins maintain a single tolerance standard across the full range, eliminating variability and enhancing process control. Inch sizes hold a tolerance of +0.000040"/-0, while metric sizes are held to +0.0010mm/-0, with roundness limited to 0.000020" (0.0005mm). Each gage is engraved with its size, enabling immediate identification and helping to prevent time loss or measurement errors during use.

These Hardened Steel Gauge Pins are cold stabilized and heat-treated to a hardness of Rockwell C62–64, reinforcing their dimensional integrity and resistance to wear over time. Each pin is precision lapped to a finish of approximately one microinch, providing a mirror-like surface that not only enhances wear resistance but also improves handling and insertion in high-tolerance holes or features. Their extra length—ranging from 1 7/8” to 3 1/2”, depending on the diameter—offers more usable surface area and allows access to deeper features during inspections or setups.

Notably, this size range does not include Deltronic’s Insul-Grip, as these gauge pins exceed the diameter range where the grip is applicable. Instead, they feature Deltronic’s exclusive relief-style handle, allowing for effective use with or without AGD handles. This design improves grip during application, especially in conditions where oil, moisture, or gloves might otherwise compromise operator control.

Every gauge pin is supplied with a Certificate of Accuracy traceable to the National Institute of Standards and Technology (NIST), ensuring full traceability and confidence in measurement precision.
