8. Plastic nut and bolts:
All plastic screw connections should be fasten by
human hands, and the gap between screws and
fastened parts must be less than 0.1mm.
Note: Thread and head contact surface
lubricated. [/Index Value]
1. The recommended maximum tightening
torques are based on a coefficient of friction for
the thread of 0.14 (without lubrication) or 0.10
(with lubrication).
2. The tightening torques are recommended for
screws ISO 4014-4018 and ISO 4762 (tensile class
8.8). If using other types of screws please contact
ABB for clarification.
Any tightening torques that deviate from those in
the general tables (e.g. for contact systems or
device terminals) must be taken into account as
stated in the detailed technical documentation.
