You no longer have to get rid of components with torn or worn threads! The repair and reinforcement of threads is no problem with our W.TEC®INSERT COIL thread inserts. Achieve reliable reinforcement of threads for robust connections for every application!
High-strength, vibration-proof screw connections can only be achieved by high-performance, high-load nut threads. Our W.TEC®INSERT COIL thread inserts repair ripped, worn, seized or damaged threads reliably and strengthen the nut thread drastically. By using threaded inserts for thread repair, you can create robust and resistant internal threads in low-shear materials (light metal alloys, aluminium, brass, plastic, etc.)
After mounting the threaded inserts, which lay like a spiral coil in the existing thread, the components have better properties than the original thread. Ideal for thread reinforcement in light metal or mechanical engineering, in the offshore sector or in agricultural technology!
Threaded inserts made of stainless chromium-nickel steel are embedded mechanically without additional locking pins, sealants or adhesives: they can be applied to the previously prepared special thread like a commercially available screw and screwed in. The thread insert consists of a rhombically profiled wire formed into a helix in combination with a driving pin, which is removed at the predetermined breaking point after installation.
The diamond-shaped cross-section, the perfect material selection, combined with the high care in the production processes guarantee you further advantages in terms of surface quality, wear resistance, thread friction, corrosion and heat resistance.
These thread inserts according to DIN 8140 have a free running, true-to-gauge thread on the entire length. The tolerance position of the ISO thread corresponds to 6H after installation. The inserts are not coloured.
This thread insert according to DIN 8140 has not only the threading advantages of the "free running" variant, but also a screw-clamping part. One or more polygonal windings act in a clamping manner on the flanks of the screwed-in screw, so that an elastically resilient frictional connection is created.
The W.TEC®INSERT COIL thread inserts can be easily installed in existing workpieces:
First, drill the damaged thread or re-drill the core hole.
Cut or for even more resilience form the thread with the special W.TEC®Screw tap.
Screw it into the core hole, in the direction of rotation, with or without insertion tool.
Use a tang break-off tool to break off the pin with a slight blow at the predetermined breaking point and remove it.
The advantages at a glance:
As wire thread inserts repair torn threads, in case of repair you do not have to replace any workpieces or components. This guarantees you an economical repair of components. Thread inserts are successfully used for years in various industries, such as machine and plant construction, automotive, commercial vehicle, tool and special machine construction, plastics industry, military technology, aerospace industry.
Threaded inserts meet the requirements of several factory standards and can be provided through our proven supply solutions.
Every single industry requires products that are geared to very specific purposes. To support the requirements of a market holistically, we consistently analyse the current needs and future requirements of our customers.
This resulted in our W.TEC® product series with products for requirements-based solutions and industry-specific innovations. We guarantee optimal and consistent quality and first-class technical service. We can give you expert advice and best practices so that you will always find the right product, be it plastic cabs, slings, screws for thermoplastic materials or many more.
