TR Fastenings (TR), the global specialist in the design, engineering, manufacture and distribution of industrial fasteners, has been named the winner of Fastener and Fixing (F+F) magazine’s ‘Route to Fastener Innovation 2019’ award for its self-extruding EPW screw.

A record 27 products were entered into the competition and the TR screw was announced as the overall winner ahead of two runners up at Fastener Fair Stuttgart on Wednesday 20th March.

Designed, manufactured and patented at TR VIC in Italy, the EPW screw is a self-extruding, high strength thread-form fastener which creates its own female thread in punched sheet metal, thereby dramatically reducing assembly times and costs. The screw works by being aligned to the pilot hole in the sheet metal, where it then forms the extruded collar, combining the forming of the thread and the creation of a strong extruded profile, before finally tightening and clamping into the metal.

The key benefits of the EPW screw include:

Removable and strong screw joint

High stripping torque

High break loose and prevailing torque

Excellent vibration resistance, meaning it can withstand pressured environments

Combined thread forming and creation of strong extruded profile

Very high radial compression on screw shank

Standard machine screws can be used in the thread created by the EPW screw
