A220004-2 is a standard ACME nut for 2-inch diameter, 4-thread-per-inch screws, made of #660 bronze. It has a thread class of 2C and interfaces with a screw having a 2.548-18UN-3A thread form. It supports a dynamic load capacity of 20,000 lbs and a static load capacity of 64,000 lbs. The nut is designed for use with the corresponding A220004-1 screw and A220004-3 flange, and its forward driving efficiency is 35% with a torque requirement of 0.227 in-lbs per pound of load. The nut's physical dimensions and mounting compatibility are defined by the flange's 4.062-inch bolt circle with four 0.531-inch thru holes.
