Sure Ed. Heat the parts up until they turn dark red and then drop them into old engine oil. Leave them in there for a bit and then fish them out and let them drain off. Finally give them a wipe over with a rag. I did these with a small propane torch. I also did some larger bolts for a friend by placing them in a steel pot I made for melting small amounts of aluminium in and put them in the forge I made.
I've had pretty good results doing this and the larger the item the larger the container of oil should be. Big parts can really boil the oil and the smoke can catch on fire at the surface but goes out pretty quickly. Those M4 screws were dropped into a 1/4 of a beer can (beer consumed and replaced with oil). For larger parts I have a 4L steel olive oil tin that I cut the top off.
