Bolt Torque Spec Chart
In the workshopTightening specs, dry & lubed
Store name: “Bolt Torque Spec Chart”
What it is
The shop torque chart as an app. Pick a bolt size and grade — inch or metric — and get the recommended tightening torque, dry and lubricated, in ft-lb and N·m. Reverse lookup tells you what your wrench setting suits.
Why we built it
Mechanics look up torque specs constantly, and the go-to sources are ad-swamped web charts squinted at on a greasy phone — or a laminated card that only covers one system. Existing apps mostly hardcode a chart someone copied. This one computes every value from the published standards, so the details the copies miss — like Grade 2's strength drop above 3/4" — come out right.
Want one like this?
Bolt Torque Spec Chart is one of 87. We can build yours.
Every app on the shelf started as one honest problem, scoped small and built native, end to end. That’s exactly how we approach client work — designed, built and shipped, without the bloat.
