More Details

Nook Industries Offers the largest selections of rolled amce screw sizes in the industry. Rolled thread screws are cost effective and are stocked for quick delivery.

Similar in construction and materials to PowerAc™ Inch Acme Screws and Nuts, the Trapezoidal thread form screws and nuts include a centralizing (C) thread form to prevent wedging and binding. When compared to general-purpose thread forms (G), centralizing threads are manufactured with tighter tolerances and reduced clearance on the major diameter.

Bronze Inch Acme

Special high tensile bronze is selected for our smooth running, anti-wedging bronze nuts.
  • Material: Nook Bronze
  • Tensile Yield: 50,000 psi
  • Tensile Ultimate: 65,000 psi
  • Hardness: HB75
  • Dynamic co-efficient of friction: 0.125 with Nook Lubricant
