The accuracy of +/-3% clockwise provides precise torque application.  Head designed specifically for Torque Wrenches includes and enclosed head which seals out dirt and contaminants, a torque wrap design which reduces stress on gear teeth and pawls for longer life and a 10 degree ratcheting angle for permitting use in confined areas.  The innovative linear ball bearing mechanism assures superior accuracy and repeatability by eliminating friction between the spring and case, eliminates speed sensibility errors and produces a crisp, audible click over the enter torque range.  Rubber seal between ratchet head and tube keeps lubrication in, dirt and contaminants out assuring accuracy and repeatability.  Detent style locking collar allows for ease in setting desired torque and prevents the accidental change of settings.  Handles are lightly knurled and grooved providing a comfortable non-slip grip.
