Tension control bolts vs slip critical.

Bolted fastener requirements can be found in two documents the rcsc speci fication sections 4 2 and 4 3 and the aisc. The slip coefficient of a bolted connection is only a consideration for slip critical connections. Slip critical joint from structural engineering is a type of bolted structural steel connection which relies on friction between the two connected elements rather than bolt shear or bolt bearing to join two structural elements. Tension control bolts ltd offer a full range of shear wrench sales hire and repair services.

Shear and tension loads can be transferred between two structural elements by either a bearing type connection or a slip critical connection. 5 joints with astm a490 or f2280 bolts that are subject to tension or combined shear and tension with or without fatigue. Tension control bolts direct tension indicator washers turn of nut tightening calibrated wrench tightening all of these methods start with the snug tightened condi tion and so it is easy to see why these extra steps add cost. Where are pretensioned or slip critical requirements located.

Dti are equivalent to load indicating washers and system hrc is effectively the same as tension control bolts tcbs. The turn of nut method is widely used to obtain the minimum preload tension force specified for bolts in slip critical connections. When the joint could be snug tightened and not slip critical. This method consists in first snug tightening the bolts.

This first step is achieved with a few impacts of a pneumatic impact wrench or the full effort of a person using a spud wrench to bring the connected. The installation cost for bolted connections that are required to be slip critical are considerably higher than for snug tight connections and higher than pretensioned joints due to the treatment of the connected material s faying surfaces. However they may be used where oversized or slotted holes are used to increase tolerances during assembly. Downloads to incorporate our range of fasteners and shear wrenches into designs cad drawings technical and dimensional details along with quality certificates and installation documents are available to download.

Preloaded bolts are seldom used in buildings where fatigue and slip in service are less critical.
