Connector wrenches sometimes referred to as a torque wrench or a connector spanner, are handheld tools used for tightening or loosening different types of connectors, devices that connect electronic or other components together. Connector wrenches are designed to make assembly easy and to prevent over-tightening so that you don't damage the connector.

How does a connector torque wrench work?

Connector wrenches make it easier to precisely tighten the connectors. Depending on your connector size, they provide a secure fitment around the connector to allow you to tighten or loosen effectively.

Connector wrench types and applications:

There are different types of connector wrenches for different types of connectors. Common connectors you would use a connector wrench for, include:

• Circular connectors – used to connect and disconnect signal, power and optical circuits.
• BNC connectors – or Bayonet Neill–Concelman connectors, a radio frequency connector used for coaxial cable.
• Chassis socket connectors – used in audio applications.
• Solar cable connectors – commonly used for connecting solar panels.
• Locknuts – a type of nut-and-bolt fastener.

Look out for connector wrenches which produce an audible click when the correct tightness has been achieved.
