The Unsung Heroes: Square Head Screws

In the vast universe of fasteners, one particular hero often goes unnoticed amidst its more popular counterparts. We’re talking about square head screws, the unsung champions of stability, strength, and versatility in construction and woodworking projects. While they may not receive the spotlight like their Phillips or flat-head counterparts, square head screws undoubtedly deserve recognition for their exceptional qualities and the invaluable role they play in various applications.

A Brief History

The history of screws traces back to ancient times, with evidence of their existence found in artifacts dating back to the 1st millennium BC. However, it was during the Industrial Revolution that the modern screw and its various types, including square head screws, began to evolve.

Square head screws, also known as Robertson screws after their inventor P.L. Robertson, were patented in 1909. Robertson, a Canadian inventor, sought to address the limitations of slotted screws, which were prone to slipping and damaging surfaces during installation. His innovative design featured a square-shaped socket and a corresponding driver, providing better torque transfer and reducing the likelihood of cam-out.

Advantages of Square Head Screws

1. Reduced Cam-Out: The square-shaped socket of these screws allows for a secure engagement with the driver, minimizing the risk of slipping or cam-out. This feature not only facilitates smoother installations but also prevents damage to the screw head and surrounding surfaces.

2. Enhanced Torque Transfer: Square head screws provide superior torque transfer compared to traditional slotted or Phillips screws. This means greater control during installation and increased resistance to stripping, making them ideal for applications where high torque is required.

3. Greater Stability: The square head design offers a more robust connection between the screw and the driver, resulting in a tighter fit and enhanced stability. This makes square head screws particularly well-suited for structural applications where stability and load-bearing capacity are paramount.

4. Versatility: Square head screws are versatile fasteners that can be used in a wide range of materials, including wood, metal, and plastic. Whether you’re building furniture, framing a house, or assembling machinery, square head screws provide a reliable solution for securing components with precision and strength.

5. Durability: Due to their sturdy construction and resistance to stripping, square head screws are known for their durability and longevity. They can withstand high levels of torque without deforming or breaking, ensuring a reliable hold over time.


Square head screws find extensive use in various industries and applications, including:

  • Construction: They are commonly used in framing, decking, and other structural applications where stability and load-bearing capacity are essential.
  • Woodworking: Square head screws are favored by woodworkers for their ability to provide a tight grip without causing splitting or damage to wooden surfaces.
  • Automotive: They are used in automotive assembly and repair, particularly in areas where high torque is required, such as engine components and suspension systems.
  • Furniture Assembly: Square head screws are often used in furniture assembly due to their ability to create strong joints and withstand the stresses of everyday use.
  • Marine and Outdoor Applications: Their resistance to corrosion makes square head screws suitable for outdoor and marine environments where exposure to moisture and harsh weather conditions is a concern.


In conclusion, while square head screws may not always steal the spotlight, their significance in the realm of fasteners cannot be overstated. From their invention over a century ago to their continued relevance in modern construction and manufacturing, Square Head Screws have proven themselves to be reliable, versatile, and indispensable components in countless projects around the world. So, the next time you pick up a screwdriver and reach for a square head screw, remember the unsung hero that quietly holds it all together.
