INTRODUCTION
Torque Specification Tables
Standard Bolt Hardware & Hydraulic Connector Torques, Specifications and Information
This specification establishes general torque values to be used in bolted joints for metric and inch hardware. This
specification is assumed to apply unless another specification (standard or specified requirement) is indicated in the
repair manual.
NOTE: These Standards do not include electrical or hydraulic components, they are referred to in their specific charts
or tables.
