BS ISO 21108 Hand-held power tools — Impulse wrenches — Dimensions and tolerances of interface to power socket

This document specifies the dimensional and tolerance requirements for the interface between handheld power tools, specifically impact wrenches, and power sockets. It addresses the mechanical connection parameters designed to ensure compatibility and safe operation across various equipment types. The scope includes defining the geometric profiles, allowable deviations, and mating conditions for the interface surfaces. These specifications aim to facilitate the interchangeability of components used in industrial and commercial settings where such power tools are deployed. By establishing clear boundaries for interface dimensions, the standard supports the integration of different tool systems while maintaining structural integrity during high-torque applications. The content focuses on technical criteria necessary for the design and manufacturing of both the tool output flanges and the corresponding socket adapters. Adherence to these guidelines helps prevent mechanical failures caused by mismatched components. The document serves as a technical reference for engineers and manufacturers involved in the development of portable power equipment and their associated accessories.
