Abstract
A down-hole tool for use in an oil or gas well is provided with detachable components that are held to a body or tool housing by longitudinal mechanical fasteners disposed in a generally radial orientation. The mechanical fasteners allow for the components to be quickly removed and refurbished or replaced, while also permitting radial movement or floating of the components during operation of the tool. A spring may be incorporated to bias the components in a radial outward direction during operation.
