Frequently Asked Questions

Why are Precision Instruments wrenches so expensive?

US-made, hand-calibrated, and rated to +/-1% accuracy at mid-range. Most torque wrenches are +/-4% (click type) or +/-2% (split beam). That extra precision matters for engine builders, aviation, and critical assemblies.

Who actually needs a +/-1% torque wrench?

Engine builders, aviation mechanics, and anyone torquing head bolts or connecting rods on performance engines. For lug nuts and brake work, a $40 Tekton at +/-4% is accurate enough.
