The Robertson screwdriver stands as one of the most iconic tools in the world of mechanics and woodworking, widely admired for its design and practicality. While many are familiar with Phillips, flathead, or even Torx screwdrivers, the Robertson screw driver is a staple in specific trades, especially in Canada, where it was invented. In this article, we will explore the history, design, functionality, and uses of the Robertson screw driver, providing insight into why it remains a trusted tool for professionals and DIY enthusiasts alike.
1. The History of the Robertson Screwdriver
To truly appreciate the significance of the Robertson screwdriver, we must first understand its origins. It was invented by P.L. Robertson, a Canadian mechanic, in 1908. Robertson, who was living in Canada at the time, was frustrated with the inefficiency of slotted screws, which were prone to slipping and stripping. This problem led him to develop a more secure and practical design: the square drive screw.
Robertson’s innovation was grounded in practicality. The slotted screws used up until then had the drawback of allowing the screwdriver blade to slip out of the slot, especially when high torque was applied. His design, which featured a square recess in the head of the screw, provided a much firmer grip for the screwdriver, making it less likely to slip.
Robertson patented his invention in 1908, and it quickly gained popularity due to its improved performance. Unlike the traditional slotted screws, which required perfect alignment and were prone to damage, the Robertson screw could be driven with more precision and without the risk of slippage. It wasn’t long before Robertson’s design was recognized as a game-changer in the world of tools.
Despite its success in Canada, the Robertson screw didn’t immediately gain traction in other parts of the world, particularly the United States. This was largely due to competition from the Phillips screw, which became widely used after its adoption by the automotive industry in the 1930s. However, the Robertson screw remained a mainstay in Canada and parts of Europe, where it continues to be valued for its superior functionality.
2. The Design and Functionality of the Robertson Screw driver
The defining feature of the Robertson screwdriver is its square-shaped tip, which matches the square recess in the head of the screw. This unique design provides several advantages over traditional screwdrivers, particularly in terms of grip and ease of use. Let’s break down the key elements of this design:
Square Recessed Head
The most obvious feature of the Robertson screw is its square recess. The recess is designed to fit a square-shaped screwdriver bit, which creates a strong connection between the screwdriver and the screw. Unlike slotted screws, where the screwdriver can easily slip out of the slot, the square shape of the Robertson screw allows for a secure fit, even when high torque is applied. This eliminates the risk of damaging the screw or the surrounding material.
Precision Fit
The square recess provides a much tighter fit compared to traditional screw heads. This means that the driver is less likely to slip, which is particularly useful when working in tight or awkward spaces. The precision fit also helps prevent the screw from being stripped, ensuring a longer lifespan for both the screwdriver and the screw itself.
Increased Torque
The square recess design allows for greater torque to be applied compared to other screw types. This is because the square shape creates multiple points of contact between the driver and the screw. With more contact points, the force is distributed more evenly, resulting in better control and more efficient driving.
Reduced Wear and Tear robertson screwdriver
Because the square drive mechanism reduces the chance of slippage, there is less wear and tear on both the screwdriver and the screw. This not only increases the longevity of the tool but also ensures that screws are driven correctly the first time, reducing the likelihood of cross-threading or other forms of damage.
Versatility
The Robertson screw driver is available in various sizes to accommodate different screw sizes. From small electronics to large construction projects, there is a Robertson screw driver suitable for every job. These screwdrivers come in different lengths and handle styles, offering versatility to users.
3. Advantages of the Robertson Screw driver
The Robertson screw driver has earned its reputation over the years for providing distinct advantages, both in professional settings and among DIY enthusiasts. Some of the most notable benefits include:
1. Better Grip
The square tip provides an excellent grip on the screw, making it easier to drive the screw into the material. The design reduces the likelihood of the driver slipping out of the screw head, which is a common issue with other screw types like slotted and Phillips screws.
