500/600 (Carbureted) Torques

When tightening bolts, nuts, or screws, a torque pattern may
need to be followed to ensure uniform equal tension is applied
to all fasteners. Proper torque application prevents fasteners
from loosening or breaking in critical service. It also minimizes
wear and eliminates premature or needless repair costs.
Following uniform torque application sequence patterns
ensures optimum performance from precision machined, close
tolerance assemblies.
The most common units of torque in the English system are ft-
lb (foot pounds) and in-lb (inch pounds). In the Metric system,
torque is commonly expressed in units of N-m (Newton
Meter).
