Our Products

Our thread gages are made of oil hardened graphitic tool steel. This material offers a high resistance to wear, good anti-friction properties, and freedom from distortion. Pitch diameters are guaranteed to be in the upper half of the gage maker’s tolerance. This will further optimize wear and extend gage life.


Hard chrome finish on all standard thread plug gages at no extra cost. Special fixtures are used in a proprietary plating bath formula which allows a greater thickness of hard chrome to finish size without re-lapping.


On orders small or large, we guarantee customer satisfaction to ensure your repeat business. Call 815-675-2305 or email for a price quote.
