Here we have a set of 8 Japanese Style (JIS) Indicator Screws for your FS1-E.  

You get 8 x M3 x 25mm screws (that's 25mm measured under the head).  

Please check that these are the size of the ones you are replacing.  If different just message me the length and I will send those.

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

Please remember to use a proper philips screwdriver.

Thanks for looking!
