1986 Honda CB700SC · Spark-Plug Service Wrench Buying guide

Check the plug hex and tool length before ordering

Use the installed spark plug and available space to choose the wrench. Correct hex fit and practical access are separate requirements, particularly where other components have changed around the engine.

Parts to consider

Honda CB1100/CB1000/CB900/CB750 Spark Plug Wrench Thin-wall 18 mm plug wrench160 mm overall length with a handle that tucks into the socket; intended for 18 mm spark-plug hexes.View part

Keep plug specification separate from tool fit

The wrench fits an 18 mm plug hex. Compare that size with the plugs fitted to the engine, while checking thread, reach and heat range from the appropriate plug and service information. A tool that fits the hex does not itself identify the correct engine plug.

Check the tuck-away design and access

The handle tucks into the socket for storage. The tool’s overall length is 160 mm, so compare both the carrying space and room to work above the plugs. Follow the model-specific service instructions for removal, inspection and fitting rather than deriving them from the wrench dimensions.

Buying questions

Can the tuck-away handle be used as a calibrated torque wrench?

No. The folding handle provides leverage and compact storage, not a torque reading. Use the CB700SC plug specification and an appropriate torque tool for controlled final tightening.

Does an 18 mm wrench identify the correct spark-plug thread or heat range?

No. It identifies the plug’s hex size only. Thread diameter, reach and heat range are separate plug specifications. Confirm the correct plug for the CB700SC and then check its hex and the available space for this 160 mm tool.

How is the handle stored?

The handle tucks into the socket, giving a compact storage arrangement. Compare the stated overall length with the space in your carried tool kit before choosing it for that purpose.
