When replacing a machine screw, it may be necessary to service associated fasteners or components. These parts are often inspected or replaced at the same time.
Washers help distribute load and prevent loosening; replace if corroded or damaged.
If threads in the mating part are damaged, the insert or nut may need replacement.
Inspect brackets for cracks or deformation that may have caused fastener failure.
