Single Thread Bronze Worm

The Single Thread Bronze Worm is a right-hand threaded worm. Works will all BH-USA flat-plate hoists and gear plates with a 96-tooth worm gear (flat-plate boat hoists). Made from hardened bronze (660 or 932). Features a .754 in. bore. Match bronze worm with a cast iron 96-tooth worm gear. Featured on the BH-USA Deluxe and Standard Series of flat-plate boat hoists. Single thread means it rotates one way. The teeth of the cast iron 96-tooth worm gear fit into the grooves of the worm. The motor turns the drive belt and pulleys that turn the driveshaft and the worm.
