Thread forming screws - Import export

• Compatible with machine screw threads • Provides a high joint strength • Low loss of preload force under high dynamic and thermal loading • Effortless lead-in with low insertion torque for safe assembly • Excellent self-locking vibration resistance • High stripping torque • Allows for a reduction in installation depth

The economic adjustment to small batch sizes, we meet with our turned parts for the direct assembly in plastics and die-cast products. Any thread forms such as, thread-tapping (DIN7500), thread cutting (DIN 7513-7516) or KTG for direct screw in plastics are realized cost-effectively. Advantage is the elimination of high tooling costs, since no counter-thread in the workpiece (eg threaded inserts, nuts, etc.) is required because the direct assembly takes place directly into the workpiece. Only a given tube is required in order to screw it directly. Our turned parts replace previously cold formed parts used (so-called multi-station presses) which require high output volumes in order to achieve a reasonable price parts.

Large Quantities: produced as cold formed parts (so-called multi-station presses), which require high output volumes in order to achieve a reasonable price parts Small Quantities: Produced as turned parts - the economic adjustment to small batch sizes Fields of application: For thermoplastics, duroplastics, light alloys, metal compounds. Industrial consumers: Electrical industry, plastics processing industry, sheet metal processing industry, telecommunications, tank- and container construction.

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

are self-tapping screws designed to securely mount thin sheet metal joints. Strong screw joint Circular cross section for better thread engagement Quick alignment and low installation torque for an easy and safe assembly High stripping torque Metric compatible

are designed for optimal joint performance with lower in-place fastening costs. Trilobular thread shape Improves and expedites thread engagement and the initial thread forming Resists loosening caused by vibrations Provides a higher uniform drive Prevents internal thread stripping

is a thread-cutting fastener designed to meet the demanding requirements of thermoset plastics with easy assembly coupled with a strong, reliable joint to ensure optimized assembly performance. Provides an asymmetrical 30º thread profile, inclined towards load surface to increase friction (FR) between the application and the fastener Reduction in radial stress Reduction in back-out caused by relaxation Increase in strip resistance Elimination for the need in supplementary locking devices Optimal thread pitch allows for deeper thread engagement Increase in pull-out strength Increase in resistance to vibration loosening Increase in load-carrying capability The recessed thread root allows space for displaced material Minimization in installation torque Miniziation in the risk related to clogging and galling of threads during assembly The shank slot minimizes chip production Through hardened to Rc 33-39

is engineered for direct assembly of thin walled and flat designed thermoplastic components. Direct assembly using the Polymate30 Screw makes thin walled and flat designs possible. This leads to material savings and reduced cycle times during injection moulding. Therefore, the quality of the Polymate30 joint and the fastening component, translates into a considerable cost saving overall.

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.

FEATURES AND BENEFITS Enhancement when compared with Polymate30: • The re-designed geometrical flank allows for the 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 are a larger core and reduction in the thread pitch length, shorter fasteners and/or smaller diameters may be used. • Improved pitch provides added vibrational safety.

Coating of threads of aluminum alloys, high-alloyed, galvanized and austenitic steels to reach controlled friction values during assembly and facilitate thread forming Prevents cold-fretting Advantages and benefits Economical through low consumption (can be diluted with tap water) The coating can be checked easily through a fluorescent ingredient Tools and containers can be cleaned with water Does not contain any toxic components and is therefore sanitary harmless The water-soluble ingredients are biodegradable, the water-nonsoluble ingredients are ecologically neutral Forms a colourless, adhesive and tackfree sliding film after drying Includes an inhibitor, which prevents corrosion during the drying

There are many different processes for forming screw threads. The usual method is to machine the thread but threads can also be formed with a thread moulder. The reason is that if the thread is shaped by plastic deformation rather than by cutting, no material is lost. However, thread moulding can only be used on materials with good cold formability.
