When Was the Phillips Screw Born?

The Invention of the Phillips Screw

Who Invented it?

In the early 20th century, Henry F. Phillips noticed a common issue with traditional slotted screws slipping and stripping, causing both damage to the screw and the object it was attached to. With this problem in mind, he created the Phillips screw and patent it in 1936.

What Problem Did it Solve?

The traditional slotted screw was a standard design for centuries. However, it was frustrating to work with as the screwdriver would frequently slip out of the slot. This problem also made it difficult to use screwdrivers in tight spaces. Additionally, these screws were prone to stripping, making them a frustrating and often costly problem.

The Phillips screw was designed to solve these problems. The screwdriver would no longer slip out of the screw, and it could be used with less effort in tight spaces. With the Phillips screw, the screwdriver is inserted into the top of the screw, which fit better with the tip of the screwdriver. Moreover, the cruciform shape of the Phillips screw head was designed to increase torque and reduce slippage.

Why Was it an Improvement?

The Phillips screw was a significant improvement over the traditional slotted screw because it offered many benefits that the older design lacked. The Phillips screw offered less slippage, which helped to reduce damage to the screw and the object being attached. In addition, the Phillips screw offered better torque than the traditional slotted screw, which meant that less force was required to attach it to an object. As a result, the Phillips screw rapidly gained popularity in many industries and became a standard design.

The Phillips screw made a significant impact on industries that relied on screws, such as the automotive and manufacturing industries. The Phillips screw required less force to attach, making it ideal for building and assembly lines, where screws needed to be quickly and efficiently fastened. Moreover, this screw's ease of use and better torque made it perfect for automakers, where a large number of screws are required to be installed by hand.


The Phillips screw was invented to solve the common problems associated with traditional slotted screws slipping and stripping. It was a massive improvement over the old design, offering better torque, less slippage, and easier insertion and removal with screwdrivers. This screw's impact was substantial, and it rapidly became the standard design in many industries. The Phillips screw remains widely used today, proving that Henry F. Phillips' invention has stood the test of time.

The Adoption and Popularity of the Phillips Screw

When Was it First Used Commercially?

The Phillips screw was commercially introduced in the early 1930s, but it wasn't until World War II that it became widely adopted by the aviation industry for their production needs. This new screw was perceived as a significant improvement over traditional screws that commonly stripped, slipped, or broke under heavy tension.With the outbreak of the war, military contractors required faster, cheaper, and more efficient production of aircraft and their parts. The Phillips screw did the trick, reducing overall manufacturing time and costs. It quickly became a staple for the aviation, automobile, and consumer goods industries.

Why Did it Become So Popular?

The Phillips screw enhanced productivity and efficiency when it came to assembling or disassembling machines and tools. It required less effort when turning, which prevented over-tightening or stripping the screw head. In comparison to other screws, it tolerated greater torque, meaning it was less prone to damage or failure under stress.The Phillips screw allowed manufacturers to assemble and disassemble products at a faster rate, reducing production and maintenance time. It also reduced the likelihood of errors and accidents, thus increasing employee safety.Not only did it positively impact industries, but it also improved the consumer experience. With the Phillips screw’s signature ‘X’ shape, it increased the ease of removing or installing screws in tight or hard-to-reach spaces. The Phillips screw made its way into homes, impacting everyday tasks such as repairing appliances, furniture, and electronics.

How Has it Changed Over Time?

The Phillips screw has undergone numerous modifications or variations over the years, including different sizes, styles, materials, and coatings. Phillips screws come in different lengths and diameters, ranging from small electrical screws to larger construction bolts. These variations in size allow multiple applications, from the automotive industry to the construction industry. Today, the Phillips screw remains a valuable standard for many industries. Manufacturers have introduced different types of screwdrivers, including those equipped with magnetic tips for easier handling of screws. Another alternative Phillips screw, known as Pozidriv, has also gained popularity. It offers a slight modification to the classic Phillips design, with additional grooves that interlock the screwdriver and screw. This design helps prevent slipping and stripping during installation, making it a popular alternative for industrial and construction applications. In summary, the Phillips screw has changed the way machines are assembled, disassembled, and maintained. It has made life easier for professionals and hobbyists alike over the years, and its original innovation remains ubiquitous today. It remains a vital component in industries worldwide.

The Impact of the Phillips Screw on Today's World

How Has it Influenced Design and Manufacturing?

The Phillips screw, also known as the crosshead screw, is one of the most widely used types of screws in the world. It was invented in the early 1930s by Henry F. Phillips and was designed to solve a problem that had plagued the automotive industry for years – the difficulty of driving a traditional slotted screw without it slipping out of the head. This new design had a cruciform shape with slightly rounded corners that allowed the screwdriver to grip the screw securely and prevent it from slipping or camming out.

The Phillips screw has revolutionized the way products are designed and assembled. Its widespread use has simplified the manufacturing process and allowed for easier assembly of products. This has led to higher productivity and efficiency, as well as reduced costs. It has also facilitated the development of other types of screws and screwdrivers that are used in different industrial applications, such as Torx, Allen, and Robertson.

In addition, the Phillips screw has made it possible to design products that can be easily disassembled and repaired, even by non-professionals. This is particularly important in industries such as electronics, where complex devices need to be regularly repaired and maintained. The use of the Phillips screw has significantly reduced the time and labor required for these tasks and has made it possible for consumers to repair their own devices rather than sending them back to the manufacturer.

What Other Industries Has it Impacted?

Over time, the Phillips screw has been adopted by a wide range of industries, including construction, automotive, and electronics. Its use in construction has made it possible to build structures more quickly and efficiently, particularly in areas where heavy-duty structural screws are required. In the automotive industry, the Phillips screw is used extensively in engine and transmission assembly, as well as in body panels, trim, and interior components.

The electronics industry also relies heavily on the Phillips screw, particularly for small devices such as smartphones, tablets, and laptops. These devices require small screws that can be easily tightened and removed during assembly and repair processes. The Phillips screw's precision and accuracy make it an ideal choice for such applications.

What Does the Future Hold for the Phillips Screw?

Despite the emergence of newer screw technologies, the Phillips screw remains a popular and widely used fastener. Its durability, versatility, and reliability have made it a staple in the manufacturing and design industries for nearly a century. It is expected to continue its legacy and remain a vital component in the manufacture of products around the world.

However, as with any technology, there are always opportunities for improvement.
