Geared offset heads, which are used to fasten and unfasten nuts and bolts, permit precise and repeatable screw connections, especially in places which are difficult to access. L.SP3 consist of a uniform housing shape for all types of interfaces. This homogeneity makes it easy to expand the fastening system by adding extra components. The impressive number of product options is itself the result of the multiple combinations of a small number of standardized component assemblies. The strengths of L.SP3 include the transmission of torques with high levels of accuracy as well as the transmission of high torques in the smallest possible designs.
