  • Page 9: Recommended Fastener Torque

    RECOMMENDED FASTENER TORQUE Higher or lower torques for special applications will be specified such as the use of spanner nuts, nuts on shaft ends, jam nuts, and where distortion of parts or gaskets is critical. Lubricated torque values are based on use of SAE 30-weight engine oil applied to threads and face of bolt or nut. Avoid using thread lubricants (such as antiseize compound) because the applied torque may vary by 10 to 40%, depending upon the product used.
