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 (Pin-Key Mfg.) that are manufactured from our internally designed machines, which provides us the capability to efficiently produce your products. We specialize in producing small to mid size pins and keys 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 of; Integrity and Ethics, Respect, Innovation, and Drive. Simply put, we always respect our customers and employees so everyone does the right thing to create the best quality products for our valued customers.
