Discover more about the High Low Thread Profile Pozi Pan Head Thread Cutting Screws range.

High-low thread profile Pozi pan head thread cutting screws are specialised precision fasteners engineered to cut their own threads into plastic substrates while minimising radial pressure. Featuring a unique dual-height thread design, they prevent the splitting or bulging often associated with installing regular self-tapping fasteners into thermoplastics.

With a flat Pan Head for a large bearing surface and a Pozi drive for reduced cam-out, these self-tapping screws for plastic provide a secure, high-quality solution for modern manufacturing and assembly.

How High Low Thread Profile Pozi Pan Head Thread Cutting Screws Work

Our high-low thread profile Pozi pan head screws feature a distinct dual thread with alternating heights. A high thread for deep cutting and a low thread for stability. This design significantly reduces driving torque and radial stress in the boss, helping to prevent cracking in the plastic. This capability eliminates the need for a separate tapping process, allowing engineers to drive the screw directly into moulded pilot holes for faster, more accessible engineering.

In a real-world engineering context, these screws are vital for assembling consumer goods, such as securing the plastic housing of a handheld device or domestic appliance. An assembly engineer can drive the screw directly into the boss, knowing the product casing remains undamaged and secure, while keeping the assembly line moving efficiently.

Materials High Low Thread Profile Pozi Pan Head Thread Cutting Screws Are Made From

To ensure the best performance and longevity, our range of high low thread profile Pozi pan head screws is manufactured from:

Steel with Bright Zinc Plating (BZP): High-grade steel provides the core tensile strength required for cutting into plastics, while the bright zinc plating serves as a durable protective shield. This finish prevents the underlying metal from rusting and offers a clean, professional aesthetic, making it ideal for interior devices where visual finish is important.

Sizes and Types of High Low Thread Profile Pozi Pan Head Thread Cutting Screws Available

Accu’s range of high-low Pozi pan head screws is available in thread sizes ranging from No.5 (3.18mm) for precise fixing needs, up to No.10 (4.8mm) for heavier-duty plastic fastening. Lengths range from 3/8 inch (9.53mm) to 1 inch (25.4mm) to accommodate various material thicknesses and boss depths.

FAQs

Q: What is the benefit of a high-low thread Pozi pan head screw in plastic?

A: The alternating high and low thread heights reduce the driving torque required for installation and minimise radial stress on the plastic boss. This significantly lowers the risk of the plastic cracking or splitting during assembly, while still providing high pull-out strength.

Q: Do I need to tap a hole before using these high-low Pozi pan head screws?

A: No. These are thread-cutting screws, meaning they are designed to cut their own threads into the material as they are driven in. However, a pilot hole (usually moulded or drilled) is still required to guide the screw.

Q: What tools are recommended to install high-low thread profile pozi pan head screws?

A: For manual installation, a standard Pozi screwdriver (typically PZ1 or PZ2, depending on the screw size) is required to ensure a secure fit and prevent cam-out.
