Set Screw Lugs

Tighten the set screw for a secure connection without crimping. Mount lugs to a screw.

Stacked Set Screw Lugs

Save space on your mounting surface by installing wire vertically.

Box Set Screw Lugs

Thread these lugs onto grounding or neutral bars commonly found in panelboards. For a secure connection without crimping, tighten the set screw.

Insulated Set Screw Lugs

To prevent short-circuiting with nearby wire, a plastic cover insulates the barrel on these lugs. Tighten the set screw for a secure connection without crimping.

Lay-In Set Screw Lugs

Mount these lugs to a surface to create electrical connections without needing to cut or splice the conductor wire. For a secure connection without crimping, tighten the set screw onto the wire.

Multi-Angle Set Screw Lugs

Often used in tight spaces, these lugs allow wire to enter at several angles.

Tamper-Resistant Set Screw Lugs

With screw heads that shear off when the appropriate torque is applied, these lugs create a secure and tamper-resistant connection without crimping.

Compression Lugs

Use a compression tool to attach lugs to wire. Mount them to a screw.

Double-Compression Lugs

The barrel is longer than other lugs, so you can compress it twice for an extra-tight grip in high-vibration applications.

Heavy Duty Double-Compression Lugs

With a thicker tab and OD, these lugs are more durable and dissipate more heat from high electrical loads than standard compression lugs. They have a long barrel, so you can compress them twice for an extra-tight grip in high-vibration applications.

Slotted Double-Compression Lugs

Accommodate differently spaced screws when connecting to equipment rails or bus bars with the slotted mounting hole on these lugs. With a long barrel, you can compress them twice for an extra-tight grip in high-vibration applications.

Finish-Your-Own Double-Compression Lugs

Drill mounting holes on these lugs where you need them. With a long barrel, you can compress them twice for an extra-tight grip in high-vibration applications.

Insulated Compression Pin Lugs

Solid pins make it easy to insert stranded wire into screw-clamp connections. The plastic cover on the barrel of these lugs provides electrical insulation to prevent short-circuiting with nearby wire.
