Abstract: This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.
