#1 Jaguar Fastener Decoding (decode.fyi)

Post by sof_xke » Thu Jun 18, 2026 12:00 am

Hey everyone, long time reader, first time posting here.

I’m in the middle of restoring a ’72 E-Type V12 and realized I never shared this here. I kept having to look up Jaguar fastener part numbers by hand, so I built a small site to make it instant: decode.fyi.

You can type in a fastener code and it returns the detailed spec in plain English. It currently covers Jaguar, Triumph, and Land Rover fasteners. No login, no ads, just a simple tool I’ve been using regularly while working on the car.

Hopefully it’s useful to a few people here as well. I’d really appreciate any feedback, especially if you spot edge cases, missing codes, or anything that doesn’t decode correctly.
