The Senco 1-1/2 inch long， 7/16 inch crown， electro galvanized medium crown 16-gauge staples have had many uses over the years. Even as the codes have changed to requiring the use of more nails than staples there are still many uses for N-Series staples. They include underlayment flooring， shingle siding， vinyl siding， facia， pallets， crating and more. These N-Series staples feature the Sencote coating that allows the staple to install easily and then create a bond with the wood that gives it more holding power.
