The design resistance of a group of fasteners may be taken as the sum of the design bearing resistances F b,Rd of the individual fasteners provided that the shear resistance F v,Rd of each individual fastener is greater than or equal to the design bearing resistance F b,Rd.Minimum edge distance e 4 ( e 4 = 1.5 d 0) Minimum edge distance e 3 ( e 3 = 1.5 d 0) Minimum center-to-center spacing perpendicular to load direction p 2 ( p 2 = 2.4 d 0) Minimum center-to-center spacing along load direction p 1 ( p 1 = 2.2 d 0) Minimum edge distance perpendicular to load direction e 2 ( e 2 = 1.2 d 0) Minimum end distance along load direction e 1 ( e 1 = 1.2 d 0) Minimum end distance, edge distance, and spacing for bolt fasteners according to EN Table 3.3 (rounded up to nearest mm) Punching resistance per mm of plate thickness under bolt or nut B p,Rd / t p Shear resistance per shear plane F v,Rd īearing resistance per mm of connected plate thickness F v,Rd / t (for e 1≥3 d 0, e 2≥1.5 d 0, p 1≥3.75 d 0, p 2≥3 d 0) Design properties for metric hex bolts (Typical coarse pitch thread)
