WebPrevailing torque is defined as the driving torque required to overcome friction in a threaded fastening application, which produces no clamp load, or bolt stretch. This prevailing torque may be required to overcome intentional interference designed into the bolted joint (Nylok patches, squeeze nuts, Tri-Lobe fasteners, etc.) or unintentional ... WebFastener Torque Specs. Torque is applied to the fastener in an effort to elastically deform the bolt shank. In the case of bolts and nuts, this elastic deformation between the bolt head and the nut is critical in order to …
