Here we have a set of 8 Japanese Style (JIS) Indicator Screws for your RD250.

You get 8 x M3 x 20mm screws (that's as measured from under the head).  

Please check that these are the size of the ones you are replacing.  If different just message me the length you need.  I stock most lengths.

They are Grade A2 stainless so will not rust like the originals.

It's best to use copper slip when replacing to ensure they do not seize up in time. 

Thanks for looking!
