130 and a reaction point when using a self reacting tightening tool is illustrated the biasing fastener 100 creates a live load on the workpiece assembly 130 by providing a biasing force to the bolt 20 when the biasing fastener 100 is placed onto the bolt 20 firmly engages with the workpiece 22 and a nut 25 is tightened against the top surface 102 of the biasing fastener to begin a bolt 20 is placed through a bore hole 50 in the workpiece 22 the bolt 20 has a first end 52 then either a first version or a second version of a third embodiment fastener 100 is placed onto the first end 52 of the bolt 20 until firmly seated against a first surface 30 of the workpiece 22 a nut 25 is then threaded onto the first end 52 of the bolt 20 until contacting at least a section of the top surface 102 of the biasing fastener 100 the biasing fastener 100 is then immobilized using a device such as but not limited to a tightening device including a first socket head and a second socket head the first socket head engages the biasing fastener 39 s 100 one or more side surfaces 106 and is fixed relative to the body of the tightening tool the nut 25 is then tightened against the biasing fastener 100 thereby resiliently deforming the top and bottom surfaces 102 amp 104 of the biasing fastener 100 and reducing the surfaces 39 respective.
