Higher tensile bolts such as property class 10.9 and 12.9 have matching nuts 10 and 12 respectively. In general, nuts of a higher property class can replace nuts of lower property class (because as explained above, the 'weakest link' is required to be the tensile fracture of the bolt).sp.info Mechanical Properties of Steel Bolts, Screws and Studsp0.2) and nominal tensile strength R m, nom (yield stress ratio). So at property class 8.8 the second figure 8 = 10 x 800/1000.
