Tightness - finger, hand, arm, FT
Discussion
Just curious really - while I was at school (a while back admittedly) we were taught such terms as 'finger tight', 'wrist tight', 'arm tight', 'full tight' etc when tightening fittings. Ive always thought it a good guage and today, when doing up some short (10mm) m2 bolts thought to myself 'wrist tight' because they wouldnt have taken much more in the metal they were going into.
I was reminded of my youth and intrigued and googled to see if the terms were in common parlance but apart from FT (of course) but couldnt really find any evidence they are in use - or in fact have ever existed.
Did I just imagine it or was this ever common parlance? Granted in terms of engineering where torque wrenches etc are all used for everything they are less useful - but I just found it popping into my head and wondered if they are still used at all?

Not from experience, but what about ?
finger tight=we know
wrist tight=spanner or ratchet done up to wrist strength
arm tight=tightened with full arm span, pulling on spanner or ratchet
full tight=apply body weight
(totally made up of course, the length of the spanner/ratchet will obviously alter the resulting torque applied)
finger tight=we know
wrist tight=spanner or ratchet done up to wrist strength

Thats exactly my understanding finger tight=we know
wrist tight=spanner or ratchet done up to wrist strength
arm tight=tightened with full arm span, pulling on spanner or ratchet
full tight=apply body weight

obviously it would depend on the tool being used - and its a pretty crude guide - but its a guide nonetheless....

BFH = needs a big effing hammer
RRR = "refitting is the reverse of removal"...

Fixed that for you finger tight=we know
wrist tight=spanner or ratchet done up to wrist strength
arm tight=tightened with full arm span, pulling on spanner or ratchet
full tight=apply body weight

I always tighten more than I had to put into removal to make up for the missing bolt or screw which went pinging off into the dark, spider ridden corner of the workshop / hedge.
