Products
Riveting technology RIVNUT®
RIVNUT® Blind rivet nuts and studs to fasten high-strength nut and stud threads on thin-walled components. Your benefits at a glance: - Stable thread on thin-walled components - Installation in case of one-sided accessibility (blind installation) - Flexible use in every production step - No thermal stress on the workpiece and therefore no warpage Processed with our new RIVNUT® Automation E and RIVNUT® NEO B107 setting tool.
Thread technology SPREDLOC®
Precision threads in modern lightweight structures — efficient expansion anchoring with one-sided accessibility Your benefits at a glance: - Pre-installed, one-piece fastener - Stable stud threads according to property class 8.8 - Thread creation in formed and drilled tap holes — no holding thread required - No chips or burrs during installation - “Blind” setting method (one-sided accessibility) - Suited for a wide range of lightweight materials* *Not suitable for polymer materials susceptible to stress cracking, such as PC or PMMA.
Screw locking RIPP LOCK®
During assembly of the fastener, the radial ribs of the RIPP LOCK® fasteners press into the respective mating surface. The resulting form fit reliably prevents self-loosening of the joint. Your benefits at a glance: - Reliable anti-rotation lock - Suitable for applications up to screw strength class 12.9 - Also suitable for sensitive surfaces - Suitable for multiple reuse - High corrosion and heat resistance
Thread reinforcement HELICOIL®
Wire thread inserts for high-strength joints in low-strength metallic materials. Your benefits at a glance: - High thread strength - Increase in quality and value - Wear-resistant, low and constant thread friction - High-strength - Corrosion- and temperature-resistant Our latest generation of HELICOIL® thread technology – HELICOIL® Smart The thread insert with tang which does not have to be broken off.
