  "abstract": "The invention describes a shim imprinting tool (10) dimensioned to fit over a stud bolt (24) prior to tightening a nut (26) on that stud bolt (24), which shim imprinting tool (10) comprises an upper assembly (101) adapted to engage with the stud bolt (24), and comprising a means (101C) of exerting an outwardly-directed axial force (F<sub>imp</sub>, F<sub>pre</sub>) on the stud bolt (24); which upper assembly (101) is mounted on a lower assembly (102) adapted to transfer a complementary axial force (F<sub>imp</sub>, F<sub>pre</sub>) against the surface (21S) from which the stud bolt (24) protrudes, the lower assembly (102) further comprising a lower face (10F) arranged to contact that surface (21S), and wherein the area (A<sub>10F</sub>) of the annular lower face (10F) corresponds to the contact area (A<sub>26</sub>) of the stud bolt nut (26). The invention further describes a friction shim imprinting arrangement (1) for use in forming a bolted joint (2), comprising a plurality of such shim imprinting tools (10); and a method of assembling a bolted joint (2) using such a friction shim imprinting arrangement (1) .",
