Products & services

TR EPW Self-Extruding Screw
TR has designed, developed and patented a 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. Features & benefits 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 Standard Machine Screws can be used in thread created by the EPW Screw Can be used for electrical earth connections Suitable for both manual and automated assembly Currently EPW Screws are manufactured to order on application and can be made in a number of materials and head styles. Depending on size, the minimum economical manufacturing quantity is 20,000 to 100,000 pieces.

Enclosure Hardware
Enclosure Hardware is the wider term for products such as Locks, Locking Systems, Gaskets, Hinges, Latches, Handles, Clamps and Terminals. These products not only increase the safety of the contents inside but also improve other factors such as ease of installation and access for maintenance teams. Locking Systems are used on large door spans where one handle operates multiple locking points. These systems are modular, providing flexibility for customising to different door sizes. Locks generally provide a single locking point with a variety of keys to suit the differing inserts available. Generally operated through 90 degrees (quarter turn), but some operate through 180 degrees. There are different IP rated Locks available to suit the different service requirements. Hinges are commonly used to connect a door to its frame or supporting object, to provide a point upon where it can rotate open and closed. Some Hinges can be “handed” (left-hand or right-hand) depending on how a door will be mounted. Clamps are typically used to connect electrical conductors such as cables or terminals. Gaskets can be used as edge protection, or to provide a seal between two surfaces (such as a door and a frame), with a wide range of profile types and fixing methods depending upon the application.

Plastic and Rubber Hardware

Fasteners for Plastic

Compression Limiters
These products are used extensively in plastic mouldings as through-holes, reducing the stress generated by threaded fasteners. They play an increasingly important role in large automotive applications in particular the electric vehicle (EV) and battery (EVB) sectors, as well as other industries.

Aerospace & Defence
Certified quality, traceability and specialist manufacturing for aerospace and defence applications.
