TR Fastenings, part of the Trifast plc group of companies, has relaunched its patented EPW self-extruding thread-forming screw, engineered to significantly cut assembly time and cost.

A revolutionary fastening solution, the TR EPW creates its own internal thread in thin sheet metal and suits a wide variety of applications, including in the HVAC, automotive, electronics, medical and telecoms industries. 

Unlike traditional flow drill products, the EPW screw can be easily installed by hand with a cordless drill, making it extremely convenient and versatile. EPW works by aligning to the pilot hole in the sheet metal, forming an extruded collar and creating a robust thread profile before tightening and clamping securely, all in one easy step.

The thread-forming screw can be installed manually or via robotic systems. With a reusable design, thanks to fixtures that are easy to disassemble, EPW can be easily removed and reused for a strong and long-lasting joint. Featuring high vibration resistance and high radial compression on the screw shank ensures a superior hold and a secure assembly. The lightweight design also makes the screw an ideal solution for many industries currently facing the lightweighting trend.

Designed, developed and patented by TR Fastenings, the EPW is an innovative high strength fastener manufactured in TR’s own factory in Italy and available to global markets in a range of materials, sizes and head styles. Surface coatings include standard zinc plating, high corrosion zinc nickel and organic zinc flake.

The EPW offers cost-effective solutions to users, thanks to its versatility of use, ease of installation and its reliability. It can be used for a variety of materials, including steel measuring 0.4mm to 1mm in thickness and aluminium measuring 0.4mm to 1.5mm in thickness, complementing an already comprehensive product range that includes self-clinch fasteners, blind rivets, welding products and more.

Enrico DeAngelis, research & development at TR Italy comments: “The EPW screw represents a significant commitment on our part to provide the finest possible product designs allied to the very best in quality, functionality and versatility. Relaunching this fastener now is perfect timing as customers are coming to us for more cost-effective solutions for thin sheet metal. The success that we feel this product will bring is due to a culmination of factors, including of course the investment that TR has made.”
