Support the project
Kenatec is free, needs no sign-up and carries no ads. No page here exists to sell you anything — and the intention is to keep it that way.
The cost isn't the server, which is cheap. It's the time: checking catalogues line by line, cross-checking two sources before publishing a dimension, writing down why a number is what it is. The 647 springs from the Bordignon catalogue took a full extraction and one wrong conclusion undone along the way; the 367 O-ring sizes were cross-checked one by one against the table derived from the standard.
If one of these tools saved you half an hour, a donation helps keep the domain online and the next calculator coming.
Where the money goes
- domain and hosting
- access to technical standards and catalogues
- hours spent checking the published data
Would rather help without money? Finding a wrong number and telling me is worth more than it seems — the site is only useful as long as it can be trusted. That's what the form at the end of this page is for.
A note on payment: donations go through PIX, Brazil's instant payment system, which requires a Brazilian bank account. If you don't have one, the most valuable help is below the form — and it costs nothing.
Payment processed by Mercado Pago. Kenatec never receives or stores your card or account details.
