Phillips Drive Screws

What are Phillips Drive Screws?

Phillips drive screws, known for their distinct cross-shaped slots, are a staple in precision engineering. The cross slot, a hallmark of the Phillips head screw, offers excellent torque transmission and alignment, reducing slippage and making installation simple over their predecessors, slotted screws. This design is crucial in precision applications where detailed alignment is paramount.

How Phillips Screws Work.

Phillips screws are incredibly versatile components, commonly employed in a wide array of industries and engineering tasks. Their unique Phillips head screw design allows for an auto-aligning fit with the screwdriver, making installation fast and efficient. This is particularly beneficial in automated production environments where precision is key. From assembling delicate electronics to constructing robust mechanical systems, the Phillips drive screw in all its head profiles is able to be applied in diverse scenarios, providing reliability and efficiency.

Material Composition Of Accu's Phillips Screws.

Accu's Phillips drive screws are available in various materials, each offering unique benefits. A2 and A4 Stainless Steel options ensure corrosion resistance and durability, making them ideal for harsh environments. For high-performance applications, materials like PEEK, Polycarbonate, and Nylon offer specific advantages such as lightweight strength and thermal stability. RENY and PPS options extend our range too, catering to specialised engineering needs.

Sizes, Types, and Finishes.

Ranging from M1.2 (1.2mm) to M10 (10mm) in thread size, and 2mm to 150mm in length, our Phillips screw sizes cater to a diverse spectrum of application requirements from resto-mods to rocketry fuselage. There are many types of Phillips head screws including the popular Phillips countersunk screw variant and Phillips pan head screw.

We have a wide range of Phillips screw sizes and types to suit various engineering tasks but if you can't find what your project requires, then our custom manufacturing options allow us to meet specific demands, just discuss them with our team.

Additionally, special finishes like AccuBlack chemical blackening can provide a reflection-free matte black look and AccuLock thread locking patches enhance resistance against loosening under vibrations.

Within our product range, similar items such as Pozidriv screws and Torx screws can be considered for different applications where varied drive styles are required. These alternatives offer superior resistance to cam-out and are worth exploring based on project specifications.


Q: What are the advantages of using Phillips head screws in precision engineering?.

A: Phillips head screws offer excellent torque transmission and alignment, which is crucial in precision applications for reducing slippage and ensuring detailed alignment. They are one of the most popular drive types meaning finding a matching tool for installation is very easy.

Q: Can Phillips drive screws be used in outdoor environments?.

A: Yes, our A2 and A4 Stainless Steel Phillips screws are corrosion-resistant, making them suitable for outdoor and harsh environmental conditions, especially the A4 variant which is marine grade.

Q: Are there Phillips screws suitable for high-temperature applications?.

A: Yes, materials like PEEK and PPS provide thermal stability, making these Phillips screws ideal for high-temperature applications where tolerances must not alter.

Q: What types of Phillips head screws are there?.

A: We offer various head types including the popular countersunk, raised countersunk and pan head variants, catering to different application needs.

Q: When were Phillips head screws invented?.

A: Phillips head screws were invented in the early 1930s by Henry F. Phillips. Phillips, an American businessman, developed this design as an improvement over the flat-head screw, seeking a solution that allowed greater torque and less slippage on the assembly line. You can learn more about this in our article, The Difference Between Pozidriv Vs. Phillips.
