2.000" diameter rods. Larger sizes or special rod ends are cut threads.
Style 2 rod ends are recommended where the workpiece is secured

style 2 rod ends are recommended through 2.000" piston rod
diameters and style 5 rod ends are recommended on larger
diameters. Use style 4 for applications where female rod end threads
are required. If rod end is not specied, style 2 will be supplied.
