Table 7 - Round Cold Finished Steel Bars

Round Cold Finished Steel Bars

Hole basis fits with hole tolerances H11, H9, H8 and H7 help rationalize on standard cutting tools and gages, whereas shaft basis fits with shaft tolerances h11, h9, h7 and h6 help rationalize on standard round steel bars available in all major industrial countries. The ANSI B32.100 standard specify the above shaft tolerances and diameters, and the sizes are according to those shown in TABLE 1. How the tolerance zones apply in national standards are shown in TABLE 7 below.
