A number of mechanical components involve
torqueing bolts in circle or square patterns. The
torqueing pattern is known to all certified
mechanics, however, as a reminder, the following

the opposite side of the last fastener tightened

Chipping teeth have 4 cutting edges. They can be
rotated as they wear to use all 4 edges during the
