Bright nickel plated brass M3.5 machine screw extension studs.
These may be used to extend the length of switch & socket screws by 35mm. The perfect product for use when the box is buried too deep in the wall & the fixing screw can’t reach.
Simply screw the extension stud into the threaded lug in the wall box & then screw the plate fixing screw into the extension stud.
Ideal for use with "decorative" screw finishes.
