History of Robertson Screws
Author: S Bates Date Posted:12 January 2023
In the early 20th century, there was a man named P.L. Robertson. He was a Canadian inventor and businessman who was frustrated with the slotted screws that were commonly used at the time. These screws had a tendency to slip, or cam out, when they were being tightened, which made it difficult to secure a piece of wood or other material in place.
One day, while working on a project in his workshop, Robertson had a flash of inspiration. He realized that by creating a square-shaped socket in the head of the screw, he could prevent it from slipping and make it much easier to use. And so, he set to work designing and patenting a new kind of screw that would later be known as the Robertson screw.
Robertson's new screw was an immediate success. It was easier to use, and because it could be tightened more securely, it was also much stronger than the old slotted screws. The square shape of the socket also meant that it was less likely to become worn or stripped, making it more durable.
As the Robertson screw grew in popularity, P.L. Robertson began to manufacture and sell them in bulk. He built a factory in Milton, Ontario, and his screws quickly became the go-to choice for builders, carpenters, and DIY enthusiasts all over Canada.
Today, Robertson screws are still widely used and remain popular for their ability to provide a secure hold, and for their ease of use. They are common in woodworking, cabinetry and construction in North America, and have been granted multiple patents. P.L Robertson's invention had a lasting impact on the industry and his legacy lives on.
