Air Torque AT551U - Tightening Torque

EB AT-RP-4GU EN 15-3
Annex
15.2 Tightening torques
− All the tightening torques are intended in Nm.
− Tightening torque tolerance: ±10%.
− The tightening torques are based on a friction coefficient of 0.12 with a lubricated fixing elements (bolts or nuts) threads.
− After long operating times or use at temperatures above 80°C, the breakaway torque may be significantly higher.
