Ring Terminals

Insulated Ring Terminals

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

Noninsulated Ring Terminals

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

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.

Insulated Heavy Duty 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.

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.

Insulated Extra-Grip Ring Terminals

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

Noninsulated Extra-Grip Ring Terminals

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

90° Flag Ring Terminals

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

Stud to Quick-Disconnect Adapters

Turn screw and stud terminals into quick-disconnect connections.

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.

Hammer-On Welding Lugs

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

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.

Battery Terminal Lugs

Connect these lugs to cable with a crimping tool or by soldering.

Heavy Duty Battery Terminal Lugs

Thicker walls than standard battery terminal lugs make these more durable.

Extra-Grip Battery Terminal Lugs

Serrations on both sides lock these lugs in place.

Solder-Loaded Battery Terminal Lugs

When heat is applied, the flux and solder mixture creates a metallic bond that is nearly twice as strong as crimping or compression connections.

Screw-On Battery Terminal Lugs

Insert your stripped cable into the compression nut and tighten; no crimping or heat is required.

Electrical Connector Crimpers

Confined-Space Wire Ferrule Crimpers

Because you insert the wire ferrule from the front, this tool is useful in tight spaces.

Wire Ferrule Crimpers

These crimpers have individual square crimping slots for each wire gauge.

Battery Terminal Hammer-On Crimpers

A compact and economical alternative to standard battery terminal crimpers. Hammer the top of the pin to crimp.

Battery Terminal Crimpers

The rotating dies in these crimpers are coded to match battery cable and terminals, making it easier to select the correct die.

Battery Terminal Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Terminal and Splice Crimpers

They may look like normal pliers, but these tools have a built-in crimping die.

High-Voltage Terminal and Splice Crimpers

The rubber grip provides protection up to 1,000 volts AC.

High-Force Terminal and Splice Ratchet Crimpers

With one ton of compression force and an ergonomic design, this crimper reduces fatigue when crimping.

Terminal and Splice Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Quick-Change Terminal and Splice Ratchet Crimpers

Dies snap in and out of this tool, so you can quickly change from crimping one electrical connector type to another.

Compression Lug and Splice Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Compression Lug and Splice Crimpers

Hydraulic Compression Lug and Splice Crimpers

The most crimping force we offer—these tools have a high-pressure pumping system.
