About Quick-Disconnect Terminals

Quick-disconnect terminals provide fast and secure connections for your wiring. Because they are easy to connect and disconnect, these terminals are convenient for applications that require frequent repair or replacement. When an application calls for a 1/4" quick-disconnect, choose a terminal with a 0.250" tab width.

Twist-On Wire Splicing Connectors

Make a quick, secure wire connection without crimping.

High-Temperature Spade Terminals

Standard

Block

Able to withstand temperatures up to 900° F, these terminals have the highest heat resistance of the spade terminals we offer. Loosen your mounting screw to install—the open end eliminates the need to completely remove it.

Block terminals have square shoulders and straight sides that fit tightly in terminal blocks to prevent wire turning.

Use a crimper (not included) to install wire.
