Additional Information

Additional Information

N/A Octolok® fasteners are placed into drilled or pre-punched holes of a specific diameter recommended for each size fastener. A press applied force drives the 8 lobe forming feature into the application material forcing the material to flow into the fastener retention groove delivering excellent torque-to-turn performance whilst the retaining ring provides superior push-out values. Octolok® fasteners can be placed manually one at a time or the assembly process can be automated.
