Octolok imperial

Product catalog summary

Overview: Octolok® fasteners, including high-performance staking studs and nuts, are designed for demanding applications, offering superior torque-to-turn and vibration resistance. They are suitable for light gauge sheet materials and can replace weld-studs, eliminating painting and plating costs.

Key Features:

8-lobe symmetrical configuration for enhanced performance.
Heat-treated to SAE standard/ISO class for high strength, allowing for reduced fastener diameter and lower assembly costs.
Available in both imperial and metric sizes, with various coatings and finishes.
Automated high-speed installation reduces assembly costs.

Installation Process: Octolok® fasteners are installed into drilled or pre-punched holes. A press-applied force drives the 8-lobe feature into the material, ensuring excellent torque-to-turn performance and superior push-out values.

Dimensional & Performance Data:

Studs and nuts are available in various thread sizes, with specific dimensions and performance data provided for each size.
Material: Carbon steel SAE J429 for studs and SAE J995 for nuts.
Performance data is based on laboratory conditions and should be tested individually for precise values.

Octolok® Studs Dimensional & Performance Data øC Material: Carbon steel SAE J429 Surface: as required Thread size Underhead shape and dimensions controlled by manufacturer to meet performance requirements. Performance data shown are typical results obtained under laboratory conditions. Tests were conducted after staking studs into low carbon steel with a maximum hardness of Rockwell B70. It is recommended that each application be tested individually for precise values. For performance in materials other than steel, individual testing is a requirement. This data is not to be considered a specification....
