Wickes sell a range of exterior screws / bolts etc that have a green
coating described as "organic". Anyone know what this coating is, and
how resistant it may be ?

Probably a fluoropolymer.

They usually offer much better protection than any basic plating
process. Lots of vehicle manufacturers at the "high end" are now
routinely using them in exposed locations.
