Norton petrol tank attachment bolt, ZP, drilled head for wire (each), for pre 1935 models. Used on my 1929 16H. The bolt has no tension on it so the head should be wired with copper wire to prevent turning. Use with MA-I43 Triumph 1in tank rubbers + MA-I41 Triumph 1in cups. No shoulder so not suitable for 1935+ models Original Part Numbers: 5376; 6323; 9329 - petrol tank fixing pin
