BOM
The world's strongest axial force introduced blind bolt
The best selling product that spans over 50 years.
①When the pins separate near the fracture surface, the BOM fasteners are properly tightened.
②BOM fasteners do not require surface treatment, polishing, or filling after fastening.
③BOM fasteners have a unique design that makes them resistant to interference (vibration). It is also resistant to constituents such as salt water that cause rust and corrosion.
[Conclusion process]
1. Insert the BOM fastener into the prepared hole.
2. Apply a fastening tool to the pin tail section. The tool starts to work, and at the same time the pin tail is pulled in, the sleeve exerts a force and forms a head on the back side. During this time, the gaps between the materials are removed.
3. The anvil performs swaging on the fixed groove on the pin side.
4 ・ Drawing on tools continues, and the fastening process ends when the pin tail is removed.
