It's the knee jerk reaction before any fault has been found with either fitting or I.W.that perhaps has repercushion's to the man on the spanner,good post by the way garry,what a deep thinker you are,lol
Been using an Impact wrench since 2006 , makita 14v and now the makita lithium 18v and too date I've had nothing like this happen ever , I've used top quality class b's , sgb 3a's , mills , stickys and presco's no issues at all .
To think that I would wave the the white flag at a mace alert is unthinkable what I will do is make sure if I come across any Chinese or Indian fittings use my swingover (common sense) .Thanks hatter for posting.
