RECOMMENDED FASTENER TORQUE
Higher or lower torque values 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 based on use of SAE 30wt engine oil applied to threads and face of bolt or nut.
Avoid using thread lubricants as the applied torque may vary by 10 - 40%, depending upon the product used.
