● Standard Spindle Assemblies
Spindle Assemblies are used to take up the travel of a threaded fastener as the fastener is rundown
(so the fastener does not run out of the socket or bit) This allows the tool to be advanced to the
fastener while the spindle assembly is compressed by the allowable stroke that is built in. As the
threaded fastener is rundown, the spindle will then follow the fastener as it is fastened.
