A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a threaded shaft attached. The threaded portion may be either male or female. Specifications Lubricant: Regular relubrication grease. Design: Steel/bronze. Bore diameter d: 16mm. Diameter head d2max: 43mm.
