BOM® (blind oversize mechanically locked) fasteners rivets are highstrength blind rivets designed for use in heavy-duty applications, such as vehicle construction, steel construction, container construction, railway transportation and the truck & trailer sector.
Made of steel, BOM® blind rivets offer a very high tensile and shear strength combined with the versatility that comes with one-sided installation – making them ideal for areas that are difficult to access.
Aided by a securely retained mandrel with a pre-set snap-off point, these blind rivets can transfer high static and dynamic loads. During the installation process, a high clamp force is exerted on the materials to be joined. The flush-fitting fastener creates a vibration-proof, airtight and watertight connection. Further benefits of the BOM® fastener system include the ease of inspecting whether the fastener is correctly fitted and its outstanding ability to prevent any unintended loosening.
Installation steps:
- Insert BOM® blind rivet into through-hole and apply installation tool.
- Operate the installation tool to apply centric tensile force to the mandrel. As the footprint swages, the parts to be connected are pressed together.
- Once the blind side footprint is fully formed, the collar is cold-formed into the grooves of the mandrel.
- Keep pulling the installation tool back until the mandrel snaps off at the pin tail. The tool will automatically pull away from the swaged collar
