tool, if employed, must be used with enough care not to get them seized.
• For * marked screws, bolts and nuts on the table, apply engine oil to their threads and seats before
tightening.

the nominal outside diameter in mm of the threads. The pitch is the nominal distance in mm between two
threads.
