The Robertson screw head, also known as the square screw drive, is a type of screw drive that has been widely used in construction, furniture assembly, and other industries. It is named after its inventor, Peter Lymburner Robertson, a Canadian businessman who patented the design in 1908. In this article, we will delve into the history, design, and applications of the Robertson screw head, as well as its advantages and disadvantages compared to other types of screw drives.
History of the Robertson Screw Head
The Robertson screw head was invented by Peter Lymburner Robertson, who was the owner of a screw manufacturing company in Milton, Ontario, Canada. At the time, the most common type of screw drive was the flathead, which was prone to slipping and stripping. Robertson recognized the need for a more reliable and efficient screw drive system, and after experimenting with different designs, he developed the square screw drive. The design consisted of a square-shaped socket in the screw head, which was driven by a corresponding square-shaped tool.
Early Adoption and Popularity
The Robertson screw head quickly gained popularity in Canada, particularly in the construction industry, where it was used for assembling furniture, decking, and other wood products. The screw head’s unique design provided a number of advantages, including increased torque and reduced slipping, which made it ideal for driving screws in wood and other materials. As the popularity of the Robertson screw head grew, it began to be adopted by other industries, including manufacturing and automotive.
International Recognition
Despite its widespread use in Canada, the Robertson screw head was not widely recognized internationally until the mid-20th century. In the 1950s and 1960s, the screw head began to gain popularity in the United States, particularly in the construction and furniture industries. Today, the Robertson screw head is recognized and used internationally, and is considered one of the most reliable and efficient screw drive systems available.
