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

• 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

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 to deliver cost-effective optimal joint performance for thin sheet metal applications. Tapered Thread Under Head Maintains full thread major diameter immediate to the surface Undercut Head Material extruded by the screw is absorbed while the under-head contact area is increased allowing for enhanced thread engagement and resistance to stripping Rounded Tip Provides easy entry into small holes with self-extrusion of the sheet metal as well as increase resistance to stripping Trilobular Build Provides resistance to loosening caused by vibration. Available with all Drive System Significantly extends tool life Ideal drive system for maximum torque transfer

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

Variable speed adjustment enables you to select optimum screw tightening speed Equipped with bit grounding mechanism Compliant with CE and UL standards

The Flowform® screw is a polygonal screw based on TAPTITE 2000®, which makes use of the technology known as "flowhole-forming" in manufacturing processes. Using this technology the Flowform® screw causes the sheet metal to heat, using a combination of axial force and relatively high screwdriver speed . Once the material has been penetrated the polygonal shape of the screw forms a calibrated metric female thread which can accept a metric screw in the event that a repair is required. After the torque-controlled assembly process the formed through-hole adjusts optimally to the contours of the screw. This gives the following advantages: Higher process reliability in the screw fastening with the option of a larger screwdriver shut-off window More flexibility when selecting the screwdriver, and more straightforward monitoring of the assembly process. In addition the Flowform® screw considerably reduces screw-in times.

Using Sheetite® ensures that in metal-joining applications, you can eliminate work processes such as thread tapping, and also dispense with additional fastening elements. The fastener is screwed directly into a metal rim-hole or a pre-drilled metal sheet, using existing plant and equipment. The polygon-shaped cross-section geometry in the thread-tapping section of screw's shaft ensures that the thread is chiplessly formed, so that if a repair is needed it can accept a conventional threaded screw. reliable low cost flexible easy to assemble very stable reduces number of variants

A non-detachable fastening for sheet metals can be produced at optimum cost by using self-clinching screws under the brand names of RIVTEX® (for sheet thicknesses between 0.75 and 2.00 mm) and STRUX® (for sheet thicknesses between 2.0 and 5.00 mm). The clinching technology is suitable for steel and aluminium sheets, causes very little cost in inspection and control, and allows several clinch screws to be processed in a single stroke.
