ROLLED THREADS : Rolling threads results in best quality highest

-strength thread because of; (1) more accurate and uniform
thread dimensions, giving a better fit between threaded
parts and fewer concentrated loads at points of misfit;
(2) smoother thread surfaces &, thus, fewer scratches
and other markings to initiate cracks, or galling; and
(3) higher yield, tensile, & shear properties to better
withstand service loads.

ECONOMY : Fewer high strength bolts are required

than M. S. bolts and rivets. Drilling of close holes is
not required. Overall weight the structure will be very
light.

SIMPLICITY : A minimum of skill is required in tightening

and the operators need only to follow a few simple rules.
