For a 1970 Honda CB100K0 oil-service order, begin with the drain opening you actually have. The featured magnetic plug has a 12mm diameter and 1.5mm thread pitch; compare those details with the removed plug before treating it as a replacement.

1970 Honda CB100K0 · Oil Service Buying guide

Check the drain plug before oil service

This selection focuses on the magnetic drain plug. Its dimensions and replacement reference help with ordering, while the sealing arrangement and condition of the opening still need a separate check.

Parts to consider

Honda CB Magnetic Oil Drain Plug Magnetic Drain Plug12mm-diameter plug with 1.5mm thread pitch; replacement reference 92800-12000.View part

Related parts: 12mm drain-plug crush washer

Identify the thread, not just the head

A similar-looking bolt head does not establish drain-plug compatibility. Use the specified 12mm diameter, 1.5mm pitch and reference 92800-12000 to compare this option with the plug removed from the engine. Altered threads need their own identification before ordering.

Keep sealing parts on the checklist

The linked crush washer measures 12 × 18 × 1mm and has explicit 1970–72 CB100K application. Compare its dimensions with the removed washer and seating area. Washer inclusion with the magnetic plug is unconfirmed, so check the supplied contents before adding a separate one.

Ordering questions

Is a washer definitely supplied with the plug?

Washer inclusion is not confirmed in the current written product details. Check the supplied contents before placing the order, then choose any separate washer by the drain plug and its seating arrangement.

Can I use it in an oversize drain-thread repair?

Do not assume so. This plug is specified as 12mm with 1.5mm pitch. Identify the dimensions of the repaired opening and match them before deciding whether this replacement is suitable.

What are the dimensions of the separate crush washer?

The linked washer is 12 × 18 × 1mm. Compare all three dimensions with the removed part and the plug’s seating area, especially after a thread repair; fitting over the threaded section alone is insufficient.
