1985 Honda CB700SC · 18 mm Plug Wrench Buying guide

Choose the plug wrench for hex size and access

Identify the hex on the installed plugs, then assess the recessed access and room for the tool. A matching motorcycle category cannot replace those practical checks on a modified engine bay.

Parts to consider

Check the actual plug hex

The tool fits an 18 mm spark-plug hex. Compare the plugs on the motorcycle before choosing it, particularly if their specification is uncertain. Thread diameter, reach and heat range are separate engine requirements and should be checked using the correct plug and service information.

Plan a usable access route

The thin-wall tool is 160 mm long and its handle tucks into the socket for storage. Check that it can reach and operate around the fitted components. Use the CB700SC manual for the service procedure and verify the plug specification separately.

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 compact is the wrench for storage?

The handle tucks into the socket for storage, and the tool has a stated 160 mm overall length. Compare that size with the tool space available on the motorcycle before choosing it for a carried kit.
