Discover more about the 30° Thread Profile Pozi Pan Head Screws range.
30° thread profile pozi pan head self-tapping screws for plastic, are precision fasteners, engineered specifically for creating robust joints in modern manufacturing, specifically with plastics and 3D printed materials.
These screws feature a reliable pozi drive for secure installation, a low-profile pan head and a specialised 30° thread profile. This acute thread angle is the key innovation, designed to slice cleanly into the mating material.
How 30° Thread Profile Pozi Pan Head Self-Tapping Screws Work
The primary innovation of this screw is its unique 30° thread profile, this sharp thread angle is designed to slice cleanly into plastic. This action forms a precise mating thread with minimal radial force, effectively preventing the material from bulging, cracking or splitting along 3D print layer lines.
The pan head provides a wide, flat bearing surface on the underside. This design is excellent for securing thin or soft plastics, as it distributes the clamping load evenly across the surface, preventing the screw from pulling through or causing damage.
The pozi drive offers superior grip and torque transmission. The design significantly reduces the risk of cam-out, allowing for a more confident and reliable installation.
When fabricating retail displays from brittle plastics like acrylic. The 30° thread profile is the perfect option for slicing into the material without causing cracking. The pan head's wide base then secures the thin sheet, preventing pull-through and ensuring a durable, professional finish.
Materials 30° Thread Profile Pozi Pan Head Self-Tapping Screws Are Made From
To ensure performance across various applications, these screws are offered in two distinct materials:
- Steel (1022): A high-strength carbon steel perfect for general-purpose use and indoor prototypes where structural integrity is the top priority.
- Stainless Steel (A2): Provides excellent resistance to corrosion and rust, making it the ideal choice for components in humid environments or products exposed to the elements.
Sizes and Types of 30° Thread Profile Pozi Pan Head Self-Tapping Screws Available
Our range is built to accommodate everything from micro-assemblies to larger engineering projects, with thread sizes from 1.8mm to 6mm and a wide variety of lengths ranging from 5mm up to 40mm to match your application's functional needs.
Our steel screws are available with a durable bright zinc plating or a sleek black zinc plating, while our A2 stainless steel screws can be supplied untreated or with our AccuBlack finish.
FAQs
What is the benefit of a 30° thread profile?
The sharp 30° angle is specifically designed for softer plastic materials like thermoplastics and 3D prints. It slices into the material and forms a thread with lower radial force, which prevents the plastic from cracking, bulging or splitting.
Why choose a Pozi drive over a Phillips drive?
The pozi drive has extra contact points that provide a much more secure engagement with the driver bit. This allows for more torque to be applied when fastening and reduces the risk of cam-out.
Do these screws require a pilot hole?
Yes. These are self-tapping screws, designed to be installed into a pre-drilled or pre-moulded pilot hole. The screw then cuts its own precise thread as it is driven in, ensuring a tight, secure fit.
