FASTENERS & FIXINGS
TR launches the EPW, a self-extruding
high strength screw for thin sheet metal
TR Fastenings (TR), global specialist in the
engineering, manufacture and distribution of
industrial fasteners, has designed, developed
and patented a new fastening solution, the
EPW thread-forming screw for thin sheet
metal.
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 re-usable strong screw
joint
• High stripping torque
• High break loose and prevailing torque
• Excellent vibration resistance
• Combined thread forming and creation of
strong extruded profile
• Very high radial compression on screw
shank
automotive, electronics, technology, energy,
medical, telecoms and general industry
sectors.
Depending on size, the minimum economical
manufacturing quantity is approx. 20,000
pieces. A fully interactive animation of the
EPW and how it works can be viewed on the
dedicated product page on the TR website:

• Standard machine screws can be used in
the thread created by the EPW screw
• Can be used for electrical earth
connections
• Suitable for both manual and automated
assembly
The screw is designed to function best in
thin sheet materials, typically Steel (0.4-1mm
thick) and Aluminium (0.4-1.5mm thick). They
are available in a variety of surface coatings
from standard Zinc plating to Zinc Nickel
and organic Zinc flake for higher corrosion
resistance. The screw is suitable for use in a
variety of applications for home appliances,
Karol Gregorczyk, TR VIC Sales and
Development Director, comments:
“We are committed to providing the highest
possible service to our customers, both in
terms of the quality products we manufacture
and how we deliver and distribute those
products. The development and launch of the
new EPW screw is a culmination of the hard
work and talent of our TR VIC Italy design
team, as well as the significant investment TR
has made in the factory.
“The EPW screw will allow our customers
to make significant improvements to
their manufacturing processes, reducing
production times, increasing efficiency and
cost-effectiveness.”
