Deltronic Thousandth Step (.001” on Half Thou) Heat Treated Gage Pin Sets (Inch) - THH25

The Deltronic THH25 Thousandth Step Heat Treated Gage Pin Sets offer precision-engineered measurement solutions for professionals requiring ultra-fine dimensional analysis centered around half-thousandth nominal sizes. Designed for inspection environments where conventional nominal sizes don’t provide the granularity needed, the THH25 Heat Treated Gage Pin Sets include a nominal gage that lands precisely on a half-thousandth (e.g., .2445") and are flanked by 12 gages increasing in .001" steps and 12 decreasing in .001" steps from that midpoint value.

These Heat Treated Gage Pin Sets are manufactured to Deltronic’s stringent Class X standards, with a tolerance of +.000040"/-.000000", ensuring absolute dimensional integrity. Each pin is heat treated and cold stabilized to maintain long-term reliability and stability in high-precision applications. The precision-lapped finish offers superior wear resistance and mirror-like surfaces ideal for smooth insertion into bores and precise fit verification.

THH25 sets provide exceptional value in quality control environments, particularly when verifying hole sizes that require finer resolution around half-thousandth tolerances. Typical applications include zeroing comparators, snap gage calibration, micrometer checks, establishing centerlines, layout work, and staging for critical inspections. These sets enable inspectors to narrow down precise hole sizes and assess dimensional drift with unmatched accuracy.

By offering nominal values that fall on half-thousandth increments, the THH25 series expands the flexibility and utility of Deltronic’s Heat Treated Gage Pin Sets portfolio. The sets are fully traceable to the National Institute of Standards and Technology (NIST), ensuring compliance with quality assurance and calibration protocols.
