# Hardware Components

## McMaster Carr

McMaster Carr is an industry-trusted hardware and tooling supplier. They are a dependable supplier with good customer service and extremely speedy delivery. Their huge selection of parts, specs (even have nuclear reactor grade stuff no joke), and super fast turnaround (order to door in 24 hours in some cases) make them an ideal choice for purchasing critical components during development. The convenience comes at a cost though, McMaster Carr seemed to be on the more expensive end in our experience, while some more specialty components cost much more than other suppliers. However, if certain critical part specs are critical for a project, McMaster Carr is a reputable supplier you can trust.

McMaster Carr offers free CAD models of all their parts! Super handy! Don't waste your time modeling hardware like screws and fixtures.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.k9rockettech.com/vendors-and-supply-chain/hardware-components.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
