About
Tight-It-Up is a free Android app that gives you the correct wheel lug nut and bolt tightening torque for a car, by make, model and year — in lbf·ft, N·m and kgf·m. It is built for mechanics and drivers who want a fast, offline reference in the shop or at the roadside.
Why it matters
Tightening wheel fasteners to the right torque keeps wheels from coming loose and prevents broken studs and stripped threads. It's good practice to re-check the torque after a wheel service and periodically afterwards.
