I bought a Powerbuilt at Pep Boys once when I needed one on a road call. It literally disintegrated on first use. It was a micrometer type. I torque almost everything from head bolts, bearing caps, flywheels, water pumps, intake and exhaust manifolds, valve covers and crank cases; everything. I own about 15 torque wrenches. Brands include 2 Snap-On, 1 Proto, 5 Williams, 1 CDI, 3 Duro, 1 Seekonk, 1 moss berg, probably forgetting a couple. I would never buy a substandard one if I could help it. Some things are worth paying the money for.
