FASTENERS & SEALING
PERFORMING IN PLASTIC E
Advancing screw performance in plastic materials with an optimised thread profile
fficient and effective operations, whether this be across automotive applications, domestic
appliances or industrial machinery, depend on the need for reliable screws, bolts, washers, clips and more. As manufacturing firms continue to innovate and expand their technical offerings to these industries, technological advances in high- performance fasteners are crucial. One company expanding its product
range to meet these demands is TR Fastenings, which has launched its new Plas-Tech 30-20 screws to the market to provide advanced fastening performance in a wide variety of plastic materials. Developed in-house, the new screws have been added to the company’s established Plas-Tech range which caters to the global automotive, technology and infrastructure, and health and home markets.
AN IMPORTANT ADDITION The new Plas-Tech 30-20 screws have been designed with an optimised thread profile to give enhanced performance in plastic materials when compared to conventional thread-forming screws. The screws have been specially developed to offer several advantages over such conventional screws in plastic, featuring a 20% finer pitch and lower flank angle to improve axial resistance. Meanwhile, a reduced thread angle lessens axial displacement and an up to 25% higher thread fill improves maximum joint strength. Additionally, the screws have been engineered to deliver smoother installation that heightens resistance to vibration. “The TR engineering team
worked as a single unity with our manufacturing sites in Europe and Asia to optimise the production process to achieve consistently high- quality products, true to the intended design,” says Sven Brehler, Director of Engineering at TR Fastenings. “This enables our high-volume customers to

create dependable joint performance, especially when using high-speed automated or robotic installation.” Looking at the key features of the
screw, the Plas-Tech 30-20 offers minimal radial stress thanks to a faceted thread profile which directs material flow. The full engagement of the screws’ self-locking angled thread design avoids loosening and delivers enhanced vibration resistance, while a large core thread profile provides high torsional and tensile strength. The screws’ optimal thread pitch ensures fastener engagement with a minimum number of rotations, keeping installation times to a minimum. Additionally, the screws are reusable, and can be removed and reinstalled several times.

MULTIPLE OPTIONS The Plas-Tech 30-20 range includes pan head, flange head and countersunk screw varieties, enabling customers to choose the ideal option for individual applications. Thread diameters are 3mm, 4mm, 5mm and 6mm, while available lengths range from 6mm to 30mm. The screws’ innovative design allows for the screw threads to displace the surrounding plastic and strengthen the fix in the process. The screws can be installed with a
calibrated pneumatic or electric driver and are particularly suited to robotic assembly processes. With standard drivers, installation is quick and stress-free.
