FC A School Tools Practice Test

An adjustable hook spanner is built to grip a part by a hook that can be sized or moved to fit around the outside of the object. The adjustable hook lets you tailor the reach so the hook sits securely around the feature, providing a firm grip for turning without slipping. That adaptability is what makes it ideal for parts of varying sizes or shapes. By contrast, a fixed hook has only one size and can’t accommodate different objects, so it won’t always grip securely. Hose coupling isn’t a spanner wrench at all, but a tool for connecting hoses, and a ratcheting adapter changes drive size with a ratcheting mechanism rather than hooking around objects.
