What it is
TorqueCounts answers “how tight?” with a number you can check. Bolt torque is worked out from the published bolt standards with the method the fastener industry’s own charts use, and every step is shown. Lug nut torque is quoted from each automaker’s owner’s manual, with a link to the page it came from.
Who makes it
TorqueCounts is built and maintained by Tay Tzu Haw, a web developer based in Malaysia. It isn’t a tool maker, a repair shop or a standards body, and it isn’t affiliated with any automaker, SAE or ISO.
How it’s checked
- The calculator’s results are tested against rows of Fastenal’s published torque charts for inch and metric bolts, on every change to the site.
- Proof stresses come from SAE J429 and ISO 898-1 as published by Portland Bolt and Fastenal; thread pitches and stress areas from the published thread tables.
- Lug nut values are read on the automaker’s own site only, for the named model and year: 3995 manual pages so far, covering 443 models. Nothing is copied from forums or other lists, and nothing is filled in from another year or model. Automated tests check that each value’s units agree.
- Every page shows when its sources were last checked.
The details are on the sources and method page.
What it isn’t
A reference, not a substitute for the maker’s manual. When a vehicle, engine or machine has a torque spec, use it: it allows for the joint, gasket and fastener it was designed with.
How the site is funded
TorqueCounts is free and supported by advertising. Ads are labeled and kept out of the calculators. Advertisers have no say in what the pages say, and there are no paid or affiliate links.
