Bolts
can be loosened by heat and vibration,
therefore requiring regular maintenance
and retorquing. This unfortunately
often leads to overtorquing and,
eventually, to failure. Stage 8,
located in San Rafael, CA, has solved
this problem by designing a locking
counterbore bolt. Next to a counterbored
hole, a small slot is milled. The
bolt is then torqued to specs. A
Locking Retainer slides over the
bolt head and a snap ring fits into
a groove in the bolt head, holding
the Locking Retainer in place. This
design acts as if a small wrench
is locked on the bolt, keeping it
from turning. No special tools required
