The height of the bolt head k is only included in the representation of the bolt and not in the calculation.
When calculating the elastic resilience of the bolt head (R3), it is assumed that the bolts are standardised. The equivalent elongation length of the bolt head lSK is calculated from lSK=0.5·d for hexagon bolts and from lSK=0.5·d for cylinder head bolts.
Care should be taken that k≥lSK is.
