1972 Honda CL350K4 · Steering Stem Hardware Buying guide

Compare the stem hardware as a matched assembly

The chrome nut has a 30mm hex and replacement reference 90304-415-000. Its separate washer carries 90503-283-000; the hex measurement describes tool engagement, not the thread specification.

Keep washer and nut purchases distinct

The chrome nut is sold each, and the chrome washer is a separate product. Inspect both before deciding what to retain. Another nut in the grid is a black machined custom choice, so establish the mechanical match before choosing the finish.

Distinguish bridge washers from the stem washer

The linked top-bridge washer kit contains two washers under reference 53235-300-000. It serves a different mounting location from the stem washer shown above. Inspect the bridge and use the correct assembly procedure; new washers are not a repair for a cracked bridge.

Ordering questions

Does the nut include its matching washer?

The washer is offered separately. Inspect the existing washer and its seating surfaces, then add it only when the repair requires one; a nut purchase should not be counted as a complete hardware kit.

Can I choose a stem nut by its 30mm size?

That figure is the hex size for the tool. Compare the replacement reference and actual stem thread before selecting the nut, particularly when the forks or yokes are from another motorcycle.

Is the two-washer bridge kit the same as the stem washer?

They are different products: the bridge kit contains two washers under reference 53235-300-000, while the stem washer uses 90503-283-000. Identify the fastening location before choosing either.
