Abstract: An installation tool and method of using same for securing fastener insert elements to substrates where the fastener element is provided with a heat meltable material which serves to bond the fastener to the substrate, the installation tool comprising a controllably heated tip for contact with the fastener and a timer means for indicating when a required heating cycle has expired and the tool should be withdrawn from the fastener: the method provides the heating of the meltable material, a resin, above the meltable temperature, but not above an upper temperature beyond which a decrease in resultant bond strength would occur.
