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 eight-lobe forming feature into the application material, forcing the material to flow into the fastener retention groove.
This delivers 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.
