A support member includes a support panel and a retention element for use in mounting an associated component to the support panel. The retention element defines a bore for receiving an associated threaded fixing element which mounts the component to the support panel. A protrusion extends into the bore from a sidewall thereof. The protrusion assists in positioning the fixing member on reinsertion of the fixing member into the bore, such that the frequency of stripping of a thread of the bore is reduced.
