Doosan DA40 - Torque limit table

GENERAL INSTRUCTIONS
SHOP MANUAL
Ch 0 page 5
This tables indicates standard torque limits in Nm for the various screw and bolt qualities and dimensions. The
torques are valid for screws on the outside of the components.
Bolt quality marking
Strength marking on screws consists of two numerals that may be separated by a point (.). The numerals indi-
cate tensile and yield limits of material in N/mm².
- Numeral 1 denotes a hundreths of the tensile limit in N/mm².
- Numeral 1 x numeral 2 denotes a tenth of the yield limit in N/mm².
A bolt designated 8.8 thus has tensile limit 800 N/mm² and yield limit 640 N/mm².
Nut quality marking
The designation for nuts consists of one numeral. The numeral denotes that the nut is of equal strength to a bolt
with the same first number.
A nut of strength class 8 is thus equally strong to a bolt of class 8.8.
