hi all
torque wrenches must be calaberated often to keep correct values. it
must be perfect. if not then know its deviation. but on the other hand
if you trying to torque a bolt and or nut that has corrosion or now
with a nylon washer or some sort of lube or sealant on the treads then
it will also throw off you torque number and yoy are in the same boat
as having a bad cal on your torque wrench. just thought i would shine
light on an overlooked area.c-ya Jonce
