•Pressure Angle: 14.5° PA, 20° PA, 25° PA, 30° PA are the most common pressure angle gear tools that we stock.
··We do stock some tooling 17.5°, 22.5°, 27.5°, etc.
··(Other less common, pressure angle gear tools are available to rent or purchase as needed.)

Accurate Worm Set Measurement

We can accurately measure the center distance of your worm set on our center distance testers.

Custom Worm and Thread Form Materials

We can use a wide variety of materials including steels, hardened steels, pre-heattreat steels, stainless steels, cast iron, aluminums, delrin (aceytl), nylon, uhmw and other plastics, non-metallics (phenolics), brass and bronzes, graphite, titanium, monel, inconel. We can and have made worms and thread forms out of many other materials as well.
