Explain the Bolted Connections

a) Questions generally relate to the size of the bolt needed for a connection or

b) Number of bolts for a given loading and specified size

c) Shear capacity of bolts is given for single shear connections only.  Most common check is for shear in a bearing type connection.

d) The designation of X and N in the table for available bolt strength relates to the threads on the bolt being iN the shear plane (325-N) and not in the shear plane (325-X).

e) The bearing strength at a specific bolt hole typically does not govern a design but must be checked nonetheless.The edge distance from the bolt to the edge of the member in the direction of the applied force is crucial (L_c shown in supplied material).
