Our replacement harpoon dart shafts are 7/16 diameter and machined to accept traditional 3/8 diameter bore bronze or stainless steel harpoon darts. Made from stainless steel and are a direct replacement and fit all of our harpoons. They feature a 7/16-14 thread pattern with is standard on all L.T. Marine harpoons. 

We now offer our replacement dart shafts with and without our Patent Pending Harpoon Dart Retention System O-ring groove. (Please note every harpoon dart sold by L.T. Marine is prepped to work with the O-ring harpoon dart retention system. If you wish to use other brand generic harpoon darts with your L.T. Marine harpoon, it is advisable to use the replacement dart shaft without the o-ring to prevent fitment issues and harpoon darts not disengaging from the dart shaft)
