They are not suitable for use as driving ratchets or driving rotation. • KSRT2/ 3-C is manufactured using a lost wax casting method. • Regarding KSRTB ratchets with hubs, please note the direction of teeth, viewing from the hub side. KHK can produce ratchets which have the teeth pointed in the opposite direction as a custom order item.
