An Eccentric Adjuster is a small hardware piece in the shape of a hexagon with one offset hole. It is designed to fit into a channel on an angle-adjustable stitching machine component, such as a caster barrel. The eccentric is important because it acts as the glue that holds the bolt of the machine component firmly together. It is tightened by means of a torque wrench, an eccentric bolt is used in order to adjust the desired measure or rather the position of the inserts. Eccentric Adjuster is made available by us for use in the various places.
