Momen Kekencangan Baut

This document provides metric bolt torque specifications for different bolt sizes in Newton meters (Nm). It lists the minimum tensile strength classes for bolts from M6 to M30 and provides dry and lubricated torque specs for bolts from M5 to M36 under the 8.8, 10.9, and 12.9 property classes. Lubricating the bolts is suggested to reduce the torque needed compared to dry bolts.

Lubed means cleaned dry bolts lubricated with a standard medium viscosity
machine oil. Lubricate all contact areas of the bolts and washers. Lubricating
the bolts is the suggested method. Thread Engagement
