Special fasteners - Import export

is a special fastener designed for reliability and an easy direct assembly into thermoplastics. Enhancement when compared with Polymate30: The re-designed geometrical flank allows for optimized movement of plastic material while initiating the fastening procedure. Under static and dynamic stress, a considerable increase is ensured in the service life of the joint. At the same nominal diameter, up to 50% gain in torsional and tensile strength. As there is a larger core and reduction in the thread pitch length, shorter fasterners and/or smaller diameters may be used. Improved pitch provides added vibrational safety. SOMETIMES SMALLER IS BETTER The visuals below show the advantages of a reduced fastener length and diameter by comparing Polymate30 to Polymate20. Substitute A provides a reduction in length, whereas Substitute B provides a reduction in diameter. For both scenarios, the reduction in pitch from the Polymate20 provides a maintainted thread flank.

K-TITE high-performance thread rolling fasteners are specially designed to lower your in-place fastening costs. K-TITE fasteners form internal threads into plain holes in ductile materials upon initial installation, which: • Eliminates the need to pre-tap the nut member • Reduces problems associated with assembling screws and bolts into pre-tapped holes, such as cross-threading

Special quick release fastenings for body parts and covers

Vaccum clamping technology from AMF: flexible, fast and efficient. Vacuum technology is used to clamp the respective workpiece by a vacuum and to implement 5-side processing easily and quickly. Thanks to the special fastening, the workpieces are protected from damage. Furthermore, the time-consuming alignment of the workpieces is not required.

Every day, industries throughout the world encounter assembly problems caused by cross-threading. Cross-threading occurs when the screw is misaligned into the female thread. This creates a new thread, which destroys the female thread. Now Arnold UMFORMTECHNIK is able to supply the patented MAThread® dog-point, an innovative solution to this problem. Screws with MAThread® dog points are shorter, lighter and can be used in more applications than other special fasteners. They are easy to fit, and robust, and thus eliminate every problem that commonly occurs with regard to fitting threaded fasteners. The MAThread design allows the designer to select the point shape best-suited to feed well in the application. As the threads come into contact, the patented anti-cross thread MAThread design begins to cam over the female thread. The MAThread design now forces the two thread helixes to align every time without fail.
