Torque Specs API

75 million fastener torque specifications — lb-ft and Nm, sequences and notes — for every US vehicle back to 1955.

Torque values are scattered across factory manuals, forum posts, and paywalled shop systems. If your app tells anyone how to touch a fastener — DIY guides, shop tablets, tool integrations — you need per-vehicle, per-component values from a source you can cite. Bing's Copilot already cites ours.

What you get

  • 75M+ specs across 39,000+ verified vehicles, organized by job and component
  • Both lb-ft and Nm on every spec, plus tightening sequence and angle where applicable
  • Confidence labels; expert-verified rows flagged (a human checked the factory manual)
  • The 1955–1995 classic era included — the data no commercial provider sells at any price

Common questions

How accurate are the torque values?

The database runs a continuous accuracy program — era/applicability sweeps, deduplication, and an expert verification desk where master techs confirm values against OEM manuals; verified values propagate across engine families and are labeled accordingly.

Do you have torque sequences, not just values?

Yes — multi-step specs carry sequence numbers and angle-tightening steps where the factory specifies them.

Metric or imperial?

Both, on every row: spec_lb_ft and spec_nm.
