Values in The Tensile Strength relationship to hardness is inexact, even for the steel, unless it is determined for a specific material. Therefore, this parentheses are chart provides only very general approximate Tensile Strength values. not contained in the normal definition range for hardness checking, but are often used in a comparable measure.

Determining Metric Tolerances Table 1: Description of Preferred Fits Table 1 is pulled from the ANSI metric tolerances section of thee machinists’ handbook, which conforms to the ISO and DIN tolerances for hole basis and shaft basis fits. Table 1 provides an overview of the hole basis and shaft basis fits that make up clearance fit, transition fit and interference fit combinations.

Determining Metric Tolerances Table 2: Commonly used Hole-Basis System of fits Table 2 shows closer detail on the hole-basis system of fits than Table 1. When using the hole-basis system of fits, the smallest diameter in the hole tolerance range is fixed to the zero line (basic nominal hole size or diameter), and the clearance between the shaft and hole extends below the zero line, or negative relative to the basic nominal hole size.

Determining Metric Tolerances Table 4: IT Standard Tolerances Table 4 details the ISO-basic tolerances (International Tolerance Grades, or, “IT”) which apply to all linear sizes (external and internal sizes, diameters, lengths, widths and thicknesses). An IT-grade number establishes the magnitude of the tolerance zone, while the tolerance position letter determines where the tolerance zone is in relation to the zero line. The combination of tolerance position letter (A-X, a-x) and IT-grade number (01-8) creates the overall tolerance symbol (i.e., F8/h7 when using the shaft-basis system of fits). For nominal size range up to 500mm according to DIN 7151/ISO 286, and for nominal size range over 500mm, according to DIN 7172/ISO 286.

Determining Metric Tolerances Table 6: Tolerances for inside dimensions (holes) Table 6 details tolerances for inside dimensions (holes) based relative to the tolerance symbol. Upper and lower values are provided as either positive or negative (or zero) values relative to the nominal size chosen. Pick the range in which the desired nominal value falls into, and then either add or subtract the tolerances to find the upper and lower tolerance range for the desired nominal size. UNITS IN MM OVER

Determining Metric Tolerances Table 8: Tolerances for inside dimensions (holes) Table 8 details tolerances for inside dimensions (holes) based relative to the tolerance symbol. This table works the same way as Table 6, but is pulled from a different source (ANSI standards) and details S7 and U7 fits. Pick the nominal size value that is closest to the desired nominal size to determine the required tolerance range relative to the chosen tolerance symbol.
