This product is part of the Wieländer+Schill XSeries professional riveting technology, optimized specifically for the automotive industry, especially BMW applications. This steel blind rivet offers an ideal solution for the durable and reliable joining of materials where fastening is only possible from one side.
The product is excellently suited for the one-sided, solid fastening of various materials – for example sheet metal, plastics, or composites – ensuring OE (Original Equipment) quality fit and durability.
This steel blind rivet belongs to the XSeries professional riveting technology category in the Wieländer+Schill range. The rivet design guarantees high tensile strength and resistance to vibration, which is essential for the repair and assembly of modern vehicle body components.
Area of application:
The rivet is primarily recommended for assembly tasks where access is limited and work can only be performed from one side of the elements to be fastened. It is excellently suited for fastening body parts, covers, interior panels, and other structural or non-structural components where adherence to original BMW specifications is required.
Material quality:
The rivet is made entirely of steel, which ensures the necessary mechanical strength and long service life even under the dynamic loads of vehicles.
Packaging quantity:
The product is available in a package of 20 pieces, ideal for smaller repair jobs or testing.
The table below details the critical dimensions and physical properties of the rivet that ensure precise fit and appropriate fastening force.

The blind rivets offered by Wieländer+Schill, compliant with BMW specifications, offer numerous advantages during the body repair process:
One-Sided Access: The main advantage is that it is not necessary to access the other side of the structure for fastening. This is critically important for closed profiles, double-walled elements, or hard-to-reach surfaces.
Joining a Wide Range of Materials: Capable of securely and durably joining different materials (e.g., steel, aluminum, plastic), which is a frequent challenge in modern mixed-material car bodies.
Fast and Efficient Assembly: The riveting process is faster than welding or screwing in certain cases, especially when the appropriate riveting tool (e.g., XSeries tools) is used.
Vibration Resistance: The properly installed blind rivet excellently resists the vibrations and dynamic loads occurring during vehicle operation, preventing premature loosening of the connection.
OE Compliance: Compliance with BMW specifications guarantees that the repair meets the manufacturer's requirements, which is important for quality assurance and warranty.
To maximize the efficiency of the riveting process, we recommend the following accessory for the product:
Mouthpiece 3.2A
Part number: 700518
Description: Flat-head mouthpiece with a diameter of 3.2 mm, specifically for blind rivets.
Compatibility: Can be used with BR 20 or BR 50 type blind rivet adapters.
This mouthpiece ensures the optimal deformation of the rivet during fastening, guaranteeing a perfect seal for the 4.0 mm diameter rivet.
This detailed description and technical data help the user make an informed decision regarding the purchase of the 777243 part number, BMW specification steel blind rivet.
