INNOVATIVE PRODUCT
DESIGN, ENGINEERING AND
MANUFACTURE: THE EPW
SCREW
The EPW screw, which was designed,
developed and patented by TR, 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
TR has 31 business locations within the UK,
Asia, Europe and the USA including, eight
high volume, high-quality and cost-effective
manufacturing sites. As a full service provider
to multinational OEMs and Tier 1 companies
spanning several sectors including
electronics and automotive, TR delivers
