SEALEY AK623 3/8IN TORQUE WRENCH

A torque wrench should be in every serious mechanic’s tool box because you can do as much damage by over-tightening a nut as under-tightening it. By using a torque wrench, you’ll always tighten to the optimum tightness for that particular size or strength of bolt/stud. This is Sealey’s AK 62 3 in square drive micrometer torque wrench. It came in a moulded plastic case that protected the tool from accidental knocks that may easily upset the calibration. The instruction leaflet gave operating and safety instructions, together with a copy of the calibration certificate. The wrench looks well made, it’s finished in silver/black and covers a setting range of 0-8 0lb-ft (2 .1-108 .5nm) which although it doesn’t cover many lower settings, will (in conjunction with Sealey’s STW1012 model) tighten the vast majority of nuts. To set the wrench, simply turn the adjusting grip accordingly. If you require 34lb-ft, turn the adjuster until its level with the 30 mark, and continue to turn until the 4’ is aligned with the centre line. The rachet head is reversible, but it must be noted that this torque wrench will not tighten left-hand threads to a setting so some nuts cannot be torqued-up correctly. I tested it against my Britool and roto torque wrenches at various settings during an engine re-build and it compared very well. One criticism could be that it’s not really long enough for the maximum setting (or perhaps I’m not as strong any more) It’s worth pointing out, as with all torque wrenches, don’t forget to slacken the adjuster off after use, or the spring will weaken. So is it worth the buying? I’d say yes but bear in mind you’ll need a second torque wrench for below 0lb-ft settings. David Brown www.sealey.co.uk
