Your Trusted Pin and Key Manufacturer
In 1944 an inventor, machinist, and businessman saw a new low cost way to de-burr machined parts, so Tumbling Supplies was born. Tumbling Supplies was built from an idea that was backed by core values.
Tumbling Supplies evolved into a manufacturer of headless dowel pins and machine keys that are manufactured from our own designed machines, which provides us the capability of trouble shooting, modifying, and maintaining our equipment. We specialize in small, uncomplicated parts that we produce with reliable quality at a low cost.
To this day, Pin-Key Manufacturing is still a family owned and operated business backed by those original core values, Integrity and Ethics, Respect, Innovation, and Drive. Simply put, we always respect our customers and employees so we all do the right thing to create the best quality products for our valued customers.
