RIVKLE® – Functions RIVKLE® blind rivet nuts and studs are the most versatile solution for adding a strong reusable internal or external thread to thin-walled work pieces, with aesthetic appearance. Compatible with all substrates (steel, magnesium, aluminum, plastics, composites etc.). Corrosion protected No additional finishing is required after setting, even with coated or painted components. Provides 2 funtions: I Rivet: enables two or more sheets (a & b) of dissimilar materials (plastic & metal…) to be joined I Thread: enables an additional component (c) to be assembled and reused, if...

RIVKLE® – Process RIVKLE® is installed using a single-sided setting technique. It's often the only fastening solution for hollow sections, housings or where access is limited to only one side of a component. This simplifies the design avoiding any need for a dedicated access hole in the rear panel. RIVKLE® blind rivet nuts and studs can be fitted at any stage so bringing extreme flexibility to your production process. RIVKLE® is a captive system. Easy and simple solution: I Can be installed without operator training I Several levels of installation process control are available to enhance...

RIVKLE® blind rivet nut – Setting methods The BÖLLHOFF recommended installation is the “pull method”. RIVKLE® can also be installed using the “press method”. 1 - Pull methods The “pull method” comprises Spin on ᕡ, Insert ᕢ, Upset ᕣ and Spin off ᕤ cycles. 2 - Pull setting methods S 2-1 Stroke setting method: control of the assembly tool displacement distance The operator sets the stroke on the setting tool in accordance with the values shown in the RIVKLE® catalogue tables. The setting tool exerts the maximum pressure and automatically stops when the preset stroke is reached (mechanical...

3 - Installation force value The recommended setting force is dependent upon a combination of information coming from RIVKLE® parameters (force to obtain a good installation) and screwing parameters (tensile strength after assembly and during service). 3-1 RIVKLE® parameters Setting range = Force to obtain good installation Stroke Tolerance Stroke in max thickness

RIVKLE® – Installation 3-2 SCREW parameters When a assembly is in use, external influences generally increase the tensile strength in the screw (F1 > F0). Setting Force With correct installation, RIVKLE® exhibits the same behaviour as a standard nut. Consequences: 1. BÖLLHOFF recommends a setting force higher than the mating screw clamp load, in order to ensure that no re-setting occurs during the life of the RIVKLE®. 2. BÖLLHOFF does not recommend the use of mechanical screw-drivers for installing RIVKLE®. Installation force range per diameter & RIVKLE® material Stainless steel A4 Force in...

RIVKLE® – Material and surface treatment Stainless steel Our standard surface treatment, Zn 8K+; 8 to 15 µm; provides the highest corrosion resistance in the standard market (400 hours to Red Rust according to ISO9227). For the most demanding applications, ZnNi8A/Fe; 8 to 15 µm, can be supplemented with either a lubricant and/or reinforcement to reach 720 or even 1000 hours to Red Rust. RIVKLE® – A real nut A standard nut, when used with it’s equivalent screw grade (ex: 8.8 class screw with class 8 nut), must provide strength characteristics as dictated by recognised standards (ISO 898; ISO...
