    Ring Terminals

    Secure wire to screw connections without worrying it will pop off. A go-to for terminal blocks, batteries, and circuit breaker panels, ring terminals encircle the whole screw shank, so they stay put better than spade and hook terminals when vibrated or pulled. They take a bit longer to install, however, because you have to completely remove the screw. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.
    PVDF Insulation—These withstand higher temperatures than our other insulated ring terminals without softening and losing their grip on the wire. They prevent short circuits on and around ovens, kilns, and other heat-generating equipment.
    Noninsulated—The basic, economical option when short circuits from nearby wiring aren't a concern.

    A good choice for machinery that needs to be frequently disconnected and reconnected for adjustment and repair. These terminals pair with other quick-disconnect terminals, so you can pop them apart whenever you need to break a connection. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.
    90° Flag—Attach wire from the side when there's no room behind the terminal. The mounting tab meets the barrel at 90°, like a flag on a flagpole.
    Noninsulated—The basic, economical option when short circuits from nearby wiring aren't a concern.
    Single Crimp—Provides a secure enough grip for most jobs.

    High-Temperature Terminal and Splice Kits

    Designed for use in high-temperature applications such as motors, ovens, and furnaces, these kits include a variety of terminals and splices made of heat-resistant materials. They are noninsulated, so you can easily inspect the wire connection. Use a crimper (not included) to install wire.

    These ceramic terminal blocks keep their shape and strength at temperatures up to 1,200° F—over four times higher than standard blocks. Mount them to surfaces in ovens, kilns, and other heat-generating equipment.
    Screw-Clamp-Terminal Wire Connection—The clamp flattens the wire to resist pullout and vibration better than screw terminals. For an even stronger and more conductive connection, crimp a terminal or wire ferrule onto the end of the wire.

    Spade Terminals

    Noninsulated

    Save time when installing lots of terminals at once or adjusting a connection. Unlike ring terminals, spade terminals don't require you to remove the screw from the terminal block or other connection point. Just loosen the screw slightly, slide the terminal under the screw head, and tighten. Since ring and hook terminals hold a bit more securely, spade terminals work best when vibration and yanked wires aren't a concern. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.

    Twist-Resistant Block Spade Terminals

    Noninsulated

    The squared shoulders fit more tightly in terminal block gaps than standard spade terminals, so the wire is less likely to turn or jostle.
    Spade terminals are faster to install than ring terminals because they don't require you to remove the screw from the terminal block or other connection point. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.

    Set Screw Wire Connectors

    These connectors hold wire more securely than crimp-on connectors, so they're a better choice for high-vibration setups. They're also quicker to install and reusable because you don't crush them with a crimping tool. Tighten the set screw into the metal barrel inside the connector for a secure grip on the wire.
