Pozi Drive Screws.

Pozi Drive Screws

What are Pozi Drive Screws?

Pozi screws, a specialized type of fastener, are distinguished by their unique Pozidriv (or 'Pozi') head drive design. This design features a cross-like shape with an additional smaller cross, allowing for enhanced grip and torque. The precision of the Pozi head screw design ensures a snug fit with the drive bit, reducing the risk of cam-out, where the screwdriver slips out of the head, making them ideal for high-torque applications.

How Pozi Screws Work.

Pozi screws are versatile and function effectively in diverse scenarios, from simple DIY projects to complex engineering tasks. Their unique head design allows them to be used where high torque and precision are paramount. For instance, in assembling electronic devices or constructing metalwork frames for F1 race cars, the Pozi drive screw provides superior hold and stability, ensuring components are securely fastened with minimal risk of damage to the head or tool. Their simple design also aids in auto alignment with pozidriv screwdrivers making installation simple.

Materials of Pozi Screws.

Available in various materials like A2 & A4 Stainless Steel and Nylon, each material offers distinct advantages. A4 and A2 Stainless Steel options provide excellent corrosion resistance, ideal for both indoor and outdoor applications. Nylon pozi screws, known for their non-conductive and corrosion-resistant properties, are perfect for electrical and marine applications, offering a lightweight yet durable alternative.

Sizes, Types and Finishes.

Pozi screws come in metric sizes ranging from the minuscule M1.6 (1.6mm) to the substantial M10 (10mm), with lengths from 2mm to 150mm, catering to a wide spectrum of requirements. Accu's range also encompasses and range of different Pozi drive head types including countersunk, pan head and flanged.

Special finishes like AccuBlack chemical blackening offer a blacked-out, reflection-free aesthetic, ideal for sensitive optical instruments. Additionally, AccuLock thread locking patches are available, enhancing durability, security and providing some protection against coming loose.

Custom manufacturing options also provide pozidrive screw solutions tailored to specific needs so make sure to speak with one of our engineers if you need a custom-manufactured component.

Similar products within the same family include Torx screws and Hex screws, each offering unique benefits for different applications.


What are pozidriv screws used for?.

Pozidriv screws are used in applications requiring high torque and precision, such as in mechanical assemblies, electronics, automotive industries, and woodworking. Their design reduces slippage and wear, making them ideal for high-stress situations.

What is an advantage of a Pozi drive screw over a Phillips screw?.

The primary advantage of a Pozi drive screw over a Phillips screw is its reduced tendency to cam out. The additional ridges in the Pozi head provide a better grip, allowing more torque to be applied with less risk of damaging the screw head or the driver.

Why is it called a POZI drive?.

'POZI' drive is short for 'Pozidriv', which is a blend of 'positive drive'. Its name reflects the design's intention to create a more positive engagement between the screw and the driver, reducing slippage and improving torque transfer.

How does the material of a Pozi screw affect its performance?.

The material of a Pozi screw significantly impacts its performance. For instance, stainless steel offers corrosion resistance, titanium provides high strength with low weight, and materials like PEEK and RENY offer high thermal and chemical resilience, each tailored to specific environmental and load-bearing needs.

Can Pozi screws be used in outdoor applications?.

Yes, Pozi screws can be used in outdoor applications, especially when made from materials like A2 or A4 Stainless Steel, which offer excellent corrosion resistance, making them ideal for exposure to the elements. Special coatings and finishes can further enhance their durability in outdoor settings.
