Internal Spline Drive Tools

Our range of internal spline drive tools is designed for high-precision fastening in aerospace and advanced manufacturing environments. Ideal for installing Hi-Lok, Jo-Bolt, and similar fasteners, these tools deliver the speed, torque control, and consistency required for both production and MRO applications.

Internal spline drive tools are built for performance and longevity, featuring machined carbon fibre blades for lubrication-free operation and precision engineering rated for up to 600,000 cycles of use. This ensures smooth, reliable operation with minimal maintenance, even in demanding conditions.

We offer a variety of RPM options to suit different applications – from low-speed, high-torque models for controlled, sensitive work, to high-speed tools for fast, repeatable installation in production environments. Their compact design allows easy access in confined spaces such as airframes and structural assemblies, while smooth throttle control supports accurate fastening.
