When you say " threads " I assume you mean it strips the thread as opposed to putting one on it .  I was wondering if this could be down to vibration . Have you checked to see if all your AV mounts  are ok ?

I think some Bosch plugs have the solid end electrode and NGK are generally threaded for caps of different type. It is an aluminium connector and has no resistive element - that will be within the plug itself!

Just found a "solid" NGK plug in my spares but i put it in and the cap isnt that tight (maybe its one that ive replaced for this reason) ive check the anti vibe springs and there all in order too. oh well, ive taped the cap down for now so it doesn't jump off while in use. Its not my only trimmer so that's a good thing. (i also have the Echo 341es single sided trimmer of a similar design to the Husky) Thanks for the replies guys
