Keyhole tooling is used to fabricate a wide variety of
parts. A few examples include banjo eyes on tow trucks, storage racks, and
shelving units.
Let’s start with keyhole shelving units. Storage racks and
shelving units are the most popular use for keyhole punches and dies. The
picture below shows a perfect example. The keyholes are used to securely lock
each shelf into place. These holes also make it easy to assemble and
disassemble the shelving unit if necessary. Storage racks and shelving units
like this can be found everywhere from the shop here at Cleveland Punch to your
nearest home improvement store.
Pictured above are examples of keyhole mounts found on shelves at the CPD’s manufacturing plant.
Another example where keyhole tooling is used is tow
trucks. Many tow trucks use safety chains to secure a car, truck, or load to
the bed of the truck. How do these chains connect to the bed of the truck? The
answer, banjo eyes. These banjo eyes are fabricated with keyholes. The safety
chain is fed through the round portion of the keyhole. When tight, the chain
slides down the oblong portion of the keyhole to lock it in place. Next time
you see a tow truck take a look at the bed. There’s a good chance you’ll see
one of these keyholes.
Keyhole punches and dies would make for a great
addition to your punch and die supply if you’re fabricating parts like this.
