Graphitic Tool Steel

All thread gages are made of the finest oil hardened graphitic tool steel available. Because of the graphitic lubricant qualities in this steel, (which reduces friction) and high carbon content, it produces superior long wearing qualities.

Hard Chrome

All standard thread plugs are supplied in hard chrome at no additional cost.

  • Heat treated and cold treated for extreme stability.
  • Lapped for extra precision and longer wear.
