RodW Posted May 8, 2002 Share Posted May 8, 2002 Can anybody offer any help on these devices? I'm considering them as a way round the difficulty in terms of access for nuts/blots that are hard to get to with a torque wrench and socket (eg front suspension damper top bolts, front suspension top and bottom ball joints.) Do they work? Do you have to adjust the torque setting to allow for the fact that they move the torque wrench away from the bolt head? If so, is that an increase or decrease and how much? From where can they be obtained and their cost? etc. Are there alternative solutions? Any help much appreciated. Thanks RodW RGW Link to comment Share on other sites More sharing options...
CHRIS CLARK Posted May 9, 2002 Share Posted May 9, 2002 Most people won't have a clue as to what the heck these items are! I do as I have a lot of imperial ones from my aircraft days. V. limited use and most problems can be overcome with mainly std. kit. Link to comment Share on other sites More sharing options...

jonsharland Posted May 10, 2002 Share Posted May 10, 2002 Yup I am looking for some too for the from suspension. I have seen some metric sets in car shops about 27pounds a set of 5 or so as I only really want one size seems to be a waste of money so if anybody knows where you can get single ones at a reasonable price please let us know Link to comment Share on other sites More sharing options...
RodW Posted May 10, 2002 Author Share Posted May 10, 2002 They are effectively the end on an open ended spanner, with a hole for a square drive. Thus they can be used on a ratchet or a torque wrench, but as they are much slimmer than a socket, they will fit in spaces where a socket won't. I would still much appreciate any info regarding their effect on torque settings, as in my original post. Thanks Rod W. RGW Link to comment Share on other sites More sharing options...
sjwb Posted May 11, 2002 Share Posted May 11, 2002 Not necessarily, crows feetquestion.gif are also available as ring spanner and socket type ends. The calculation is and I am not sure how this will come out but here goes. Torque Reading = T wrench effective length X Torque desired (divided by) T wrench effective length + Extension length Torque wrench effective length is center of drive square to the lengthways center of handle. Extension length is center of drive square to center of ring end (open, socket end). Therefore, using a 12" wrench for a desired torque of 30lbf/ft with a 6" extension. = 12 X 30 12 + 6 = _360_ 18 = 20 lbf/ft read on the torque meter teeth.gif Steve B Link to comment Share on other sites More sharing options...
scooby dooby doo Posted May 12, 2002 Share Posted May 12, 2002 ah cheers! i know the things you mean. and the calculation looks just like the one i'd mentally composed before seeing you'd written it! :)) Dave Hooper - North London dmch2@lineone.net Link to comment Share on other sites More sharing options...
