Set Screw Lugs
The straight tongue improves conductivity by increasing the surface contact between the lug and your equipment. Tighten the set screw onto your wire for a secure connection without crimping. Mount lugs to a screw.
Copper lugs can be used in large power distribution systems, motors, and generators.
Aluminum lugs are more lightweight and can be used in electrical distribution systems.
