The design allows for the screw threads to displace the surrounding plastic, in the process strengthening the fix. TR Fastenings can provide bespoke engineered products and a selection of related components as well.
Plas-Tech 30-20 screws are available with various protective coatings. They are of particular importance in the automotive, technology & infrastructure and health & home markets.
According to TR Fastenings, the Plas-Tech 30-20 has been developed to offer several advantages over conventional thread-forming screws in plastic, such as:
- A 20% finer pitch and lower flank angle to improve axial resistance
- A reduced thread angle to lessen axial displacement
- Up to 25% higher thread fill to improve maximum joint strength
- A smoother installation that heightens resistance to vibration
Key features of the Plas-Tech 30-20 include:
- Minimal radial stress: the faceted thread profile directs material flow to reduce radial stress
- Superior vibration resistance: the full engagement of the self-locking, angled thread design avoids loosening
- High torsional strength and tensile strength: a large core thread profile provides high strength
- Optimal thread pitch: ensuring fastener engagement with a minimum number of rotations, keeping installation times to a minimum
- High reusability: the fastener can be removed and re-installed a number of times
The Plas-Tech 30-20 screw range includes pan head, flange head and countersunk head varieties, enabling TR customers to choose an option for each application. Thread diameters are 3mm, 4mm, 5mm and 6mm, and available lengths range from 6mm to 30mm. The design allows for the screw threads to displace the surrounding plastic, in the process strengthening the fix. TR Fastenings can provide bespoke engineered products and a diverse selection of related components as well.
The screws can be installed with a calibrated pneumatic or electric driver and are particularly suited to robotic assembly processes.
