Lugs

Set Screw Lugs

The straight tongue improves conductivity by increasing the surface contact between the lug and your equipment.

Set Screw Lugs with Offset

An offset tongue gives you extra space to insert wire.

Compression Lugs

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

Double-Compression Lugs

Compress the barrel twice for an extra-tight grip in high-vibration applications.

Screw-Down Welding Lugs

Tighten the screw with a ¼" hex key wrench for a more secure connection than Hammer-On Welding Lugs.

Hammer-On Welding Lugs

Slide these lugs onto cable and strike them with your hammer to create a durable connection.

Ring Terminals

Noninsulated Ring Terminals

Mount these terminals on a threaded screw or stud for a more secure connection than spade and hook terminals.

Insulated Ring Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated Elongated Ring Terminals

Mount these elongated ring terminals on a range of screw sizes.

Insulated Elongated Ring Terminals

The elongated ring can be mounted with a range of screw sizes. A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated High-Temperature Ring Terminals

Choose from all-metal terminals rated to 900°F or 1200°F.

Insulated High-Temperature Ring Terminals

A plastic cover on the barrel provides electrical insulation. These terminals can withstand temperatures up to 300°F.

Noninsulated Extra-Grip Ring Terminals

A serrated edge on the inside of the ring grips the mounting screw for a secure hold.

Insulated Heavy Duty Ring Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Insulated Extra-Grip Ring Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated Heavy Duty Ring Terminals

Thicker than standard ring terminals, these are more durable.

90° Flag Ring Terminals

Connect wire to a screw or stud at a right angle to fit connections into tight spaces.

Hook Terminals

Insulated Hook Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Noninsulated Hook Terminals

A hybrid of ring and spade terminals, these install without removing the mounting screw, yet resist being pulled off.

Spade Terminals

High-Temperature Spade Terminals

Able to withstand temperatures up to 900°F, these terminals have the highest heat resistance of the spade terminals we offer.

Noninsulated Spade Terminals

Loosen your mounting screw to install—the open end eliminates the need to completely remove it.

90° Flag Spade Terminals

Connect wire to a screw or stud at a right angle to fit connections into tight spaces.

Insulated Spade Terminals

A plastic cover on the barrel provides electrical insulation rated to 600 volts.

Terminal and Splice Assortments

Ring Terminal Assortments

Keep a variety of ring terminal sizes on hand.

Terminal and Splice Assortments

Use the included crimping tool to install a variety of terminals and butt splices.

Grounding Lugs for Enclosures

Create a common grounding path for not only internal components and circuits, but also your enclosure’s body.
