Deltronic Class X Plus Heat Treated Pin Gages .3873” – .6375” / 10.0375mm – 16.1925mm

Deltronic Class X Plus Heat Treated Pin Gages .3873” – .6375” / 10.0375mm – 16.1925mm

The Deltronic Class X Plus Heat Treated Pin Gages .3873” – .6375” / 10.0375mm – 16.1925mm are meticulously engineered inspection tools developed to meet the most stringent metrology and quality assurance standards. As part of Deltronic’s Class X line, these Heat Treated Pin Gages deliver consistent size and roundness tolerances across the full range, ensuring dependable performance in dimensional verification, go/no-go gauging, and layout inspection processes. Each pin is supplied with a Certificate of Accuracy traceable to the National Institute of Standards and Technology (NIST), underscoring their precision and traceability in regulated environments.

These pin gages maintain Class X tolerances of +0.000040"/-0 for inch sizes and +0.0010mm/-0 for metric sizes, with an exceptional roundness specification of 0.000020" (0.0005mm). Each pin is permanently marked with its size to eliminate time-consuming identification and reduce the risk of operator error during measurement tasks. The added value of this self-identifying feature is especially beneficial in fast-paced or high-throughput environments where efficiency and reliability are critical.

Deltronic’s proprietary relief-style handle enhances grip and operator control, allowing these gages to be used either by hand or in conjunction with AGD handles. This handle design ensures optimal handling even under oily, wet, or gloved conditions, making them ideal for both shop floor and lab use. The extra-long construction—ranging from 1 7/8” to 3 1/2”, depending on the diameter—maximizes the usable measuring surface, improving accessibility for deep features, bore alignment, and hole spacing evaluations.

Each pin gage is precision lapped to a mirror-like finish of approximately one microinch, which improves resistance to wear and promotes smooth engagement with test features. These Heat Treated Pin Gages are hardened to a Rockwell C62–64 and undergo cold stabilization, ensuring they retain their dimensional integrity under extended use and varied environmental conditions. The result is a durable, high-accuracy tool built to perform consistently throughout its service life.
