Loading along the length of the bolt puts the bolt in axial tension. Including the threads in the shear plane reduces the strength of the connection by approximately 25%. Snug-tightened connections are referred to as bearing connections Bolts in a slip-critical connection act like clamps holding the plies of the material together.Bearing type connections may have threads included ( Type N ) or excluded ( Type X ) from the shear plane(s). High strength bolts may be snug-tightened or slip-critical. Staggered bolt layout allows easier access for tightening with a pneumatic wrench when a connection is all bolted. Steel Connection is divided into two common methods: bolting and welding.īolting is the preferred method of Steel connecting members on the site. (Download FREE!)
