I am a DIY homeowner and this was only used in my personal garage, by me. Tight as the day it was purchased.
Proto Made in USA 1/4 in Torque Wrench. Scales in inch pounds and newton meters. I purchased this new for an engine rebuilt and have not used since. Looks and feels brand new. Always kept at zero and in the case, in a temperature controlled garage.
It comes with a generic black case to protect the wrench.
