Over-tightened bolts done in the wrong sequence are the number one cause of warped parts, breakage, and consequently equipment failure. As cars became more sophisticated and exactness more crucial the tools needed to service them kept pace. A good example is the torque wrench. What began as a simple unwieldy beam design, requiring eyes on the dial at all times, was sufficient where there was lots of room to move. As spacious inline six- and eight-cylinder engine compartments gave way to V-6 and V-8s with confined access the newly introduced ratcheting clicker type with no visual connection needed was the perfect answer.
Eastwood Tech Tip:
Never lubricate your garage door tracks with WD-40 or other petroleum-based products. Clean that off with solvent and lube with a dry film-based lubricant. This will eliminate contaminant buildup on the track and quiets door operation.
Notice the largest of Eastwood’s four new professional-grade aluminum-bodied micrometer clicker torque wrenches is more compact with a thinner handle and slimmer ratchet head than the lesser torque-rated competing brands shown.
Eastwood’s professional grade micrometer torque wrenches feature a dual scale. This side is metric and reads in a range of 76-338 Newton meters. The other side reads in SAE 50-250 ft-lb.
Unlike earlier clicker designs, the Eastwood micrometer clicker torque wrench does not need to be backed down to zero after every use. It can be left locked in up to three to four weeks.
Pushing this aluminum collar downward unlocks the micrometer barrel allowing metric or SAE settings to be made. Release to lock.
Modern vehicle lug nuts specify much higher torque settings often in the range of 135 ft-lb. Eastwood professional-grade torque wrenches are accurate to plus or minus 3 percent. It is a good practice to check (test) calibration once a year.
