Lugs

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.

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.

Solder and Crimp-On Welding Lugs

Solder these lugs in place, or use a crimping block and punch for the most secure connection of any of the welding lugs we offer.

Screw-Down Welding Lugs

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

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.

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 Elongated Ring Terminals

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

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 Heavy Duty Ring Terminals

Thicker than standard ring terminals, these are more durable.

Insulated Heavy Duty Ring Terminals

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

Heat-Shrink Ring Terminals

When heat is applied, the insulation shrinks and creates a seal that keeps out water, salt, and contaminants.

Solder-Loaded Heat-Shrink Ring Terminals

When heat is applied, the enclosed solder melts, creating the most secure, electrically conductive, and environmentally sealed connection we offer.

Elongated Heat-Shrink Ring Terminals

The elongated ring can be mounted with a range of screw sizes.

Noninsulated Extra-Grip Ring Terminals

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

Insulated Extra-Grip Ring Terminals

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

90° Flag Ring Terminals

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

Ring Terminal Jumper Cords

Save preparation time—these cords are ready-to-use with ring terminals on each end of a single-conductor wire.

Spade Terminals

Insulated Spade Terminals

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

Noninsulated Spade Terminals

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

Heat-Shrink Spade Terminals

Apply heat to shrink the insulation and create a seal that keeps out water, salt, and contaminants.

Solder-Loaded Heat-Shrink Spade Terminals

When heat is applied, the enclosed solder melts and the insulation shrinks, creating the most secure, electrically conductive, and environmentally sealed connection we offer.

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.

90° Flag Spade Terminals

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

Hook Terminals

Noninsulated Hook Terminals

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

Insulated Hook 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.
