Welcome to our FAQ section. Here you can find answers to the most common situations you may face in practice.
RIVKLE® blind rivet nuts are developed to meet the mechanical requirements of strength class 8.8.
The recommended pressure is 5 to 7 bar.
The B2007 should be set to the "load measurement" mode.
The P2005 is a stroke setting device. Measuring the load is not relevant.
We strongly advise not to. It could twist the component and alter its mechanical features. Some setting tools will go on default since the stroke limit is reached before the load (B2007).
We strongly advises not to.
Either the RIVKLE® is to long and requires a special anvil. Or it is a special extended anvil, please contact us.
No, a RIVKLE® setting tool with left-hand rotation should be used.
Yes, provided that adequate tools are used.
We recommend a conventional grease.
Böllhoff mandrels are designed with high-strength steel (Rm > 1,600 N/mm2 or Mpa) allowing to support the high RIVKLE® setting force. However, in case of RIVKLE® traction setting, the user has to regularly replace the mandrel of its setting tool. Indeed, the frequency of use of the setting tool can generate a fatigue phenomenon and then the mandrel breaking. Wear of the mandrel thread can also be observed. It is the erosion of the mandrel thread due to successive screwing/unscrewing friction.This phenomenon is influenced by the blind rivet nut friction coefficient.
How to identify this phenomenon:
The mandrel should be replaced, either when the mandrel is broken or when there is wear on the mandrel thread.
Replace your mandrel with a new one and try again.
Class 12.9 DIN 912 screws should be used.
It is strongly advisable to use a maintenance unit to ensure a constant operating pressure. That will increase the life span of your RIVKLE® setting tool.
Yes, very slightly.
RIVKLE® P1007/P2007/P2007PN/P2005 setting tools consume 8 liters of air per cycle. RIVKLE® P3007/P3007PN consume 15 liters of air per cycle.
Mineral hydraulic oil VG68 (Viscosity Grade) is adapted to all RIVKLE® setting tools, to the exclusion of RIVKLE® B2007 which operates with mineral hydraulic oil VG10.
The hydraulic oil should be immediately beneath the bleeder screw.
The hydraulic oil should be changed at each level 3 maintenance, or 250,000 cycles for pneumatic and electric RIVKLE® setting tools.
The RIVKLE® setting tool is covered by a 12-month guarantee as from shipping date from Böllhoff.
These are wear parts that are not covered by the 12-month guarantee.
The guarantee no longer applies.
