1986 Honda CB750SC · Plug Wrench Selection Buying guide

Identify the plug hex before choosing the wrench

The wrench’s 18mm socket and 160mm overall length provide concrete selection checks. Confirm them at the actual engine, especially if plugs or surrounding components differ from the original arrangement.

Keep tool size separate from plug specification

The 18mm dimension describes the wrench socket, not the spark-plug thread or engine compatibility. Identify the correct plug from the fitted engine’s service information, then match the tool to its hex. A suitable socket does not establish that the installed plug is the correct type.

Plan access and compact storage

The handle tucks into the socket for storage. Check the 160mm tool length and working clearance around the engine before relying on it for plug removal. Follow the correct plug and motorcycle instructions for service, rather than choosing tightening specifications from the wrench alone.

Buying questions

What should I check if different spark plugs have been fitted?

Identify the plugs and compare their hex size with the 18mm socket. Confirm the plugs themselves match the fitted engine’s service specification, then check that the wrench has suitable access.

How long is the wrench?

Its overall length is 160mm. Compare that with the available space above the plug and the surrounding components before deciding that the tool is practical for the job.

How does the handle stow for storage?

The handle tucks into the socket. Check your toolkit space and the working clearance at the engine so the compact-storage feature suits both carrying and using the tool.
