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.

PowerAc™ Inch Acme 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.

The high strength and inherent lubricity of plastic Acme and Trapezoidal nut material can result in product life that can equal or exceed conventional nut materials.
