Selection of the set screw
CAUTION
Physical injury
Risk of injury from protruding set screw.
• Please observe the information about selecting the set screw.
Use set screws in accordance with ISO 4029 with a toothed cup point. The size of the set
screw is determined by the bore made. The set screw should fill out the threaded hole as
much as possible and must not protrude beyond the hub.
