Securing a screw to a shockmount to hinder loosening upon vibration is performed by a specially formed and secured piece of wire that rests, under exertion of spring force, in the screwdriver slot of the screw. Shown in the figure is a shockmount 1 mounted onto standoff bosses 2 to the base 3 of a casing 4. Shockmount 1 is fastened to base 3 with the help of screws 5. Shockmount 1 has a screw 6 that is free to rotate about its center axis. A bracket 7 contains a tapped hole 8 through which screw 6 passes. This allows vertical adjustment and fixing of bracket 7 relative to base 3 of casing 4. To prevent loosening of screw 6 out of hole 8, a formed piece of wire 9 is provided. One end 10 of that wire is fixed by screw 5 to retain it from rotation.
