Ball Studs, Grounding Ball Studs
Features: Permanent grounding ball studs permit universal and ball stud clamps to be used for different electrical systems such as apparatus, bus bar, conductors, vehicles, reels etc. Spherical form of grounding ball stud permits installation of grounding clamp at various angles to reach the most inaccessible areas. Meets ASTM and IEC standards Material: 99.9% electrolytic tin-plated copper. Stainless steel hardware (washer, lock washer, and nut) included (if applicable).
