- Restored Service Integrity — A correctly sized tap restores clean, usable threads to fastener bores, preventing loose fastener connections that can affect structural integrity and operational safety on heavy-duty slab cutting equipment.

A tap is a precision cutting tool used in service and repair work to cut or restore internal threads inside a threaded bore. On floor saws such as the FS400LV and FS513, maintaining clean, properly formed threads throughout the machine is critical — damaged or stripped threads in fastener holes can compromise the security of covers, guards, and structural assemblies. Using the correct OEM-specified tap ensures that re-threaded bores hold to the proper torque values, keeping all fastened components securely in place during demanding concrete cutting operations.
