Abstract of the Disclosure A method of securing terminals to a distributor cap and the cap formed thereby. A molded thermoplastic distributor cap is provided which has bores formed in the towers of the cap. Die cast zinc terminals having ribs and recesses therebetween are partially inserted into the bores of the cap. With the terminals partially inserted into the cap they are engaged by an electrically heated head member which causes the terminals and cap material to heat up. When the cap material is heated to a flowable state the terminals are pushed into the cap and cap material is moved into the recesses to anchor the terminals in the cap. The terminals are provided with vent slots.
