For Class 8.8 and 10.9 M12 bolts the design shear resistance Fv,Rd has been calculated as 0.85 times the value given in BS EN 1993-1-8, Table 3.4 (§3.6.1(5))
See Clause 3.7(1) of BS EN 1993-1-8: 2005 for calculation of the design resistance of a group of fasteners
Bearing resistances may be taken from the tables for non-preloaded bolts
The shear resistances are ULS values
The slip resistances are SLS values
Values have been calculated assuming ks = 1. See BS EN 1993-1-8, Section 3.9 for other values of ks
