AS954 Aerospace sockets
AS954 Standard for High Strength Tools covers tools that are specifically designed for wrenching of 12-point aerospace fasteners. The key concept embodied in AS954 is the requirement that the wrenching tool contact the 12-point fastener away from the fastener corner, thereby reducing the tendency to round fastener corners.
Koken Sockets are made from solid material using the Cold Forming Process:
Cold forming is a manufacturing process that plastically deforms metal using dies. It allows for high speed production, little to no material waste compared to conventional machining, and creates a stronger end product due to work hardening of the material. Cold forming allows higher productivities while still maintaining high precision and complex product geometries. No heating of the material is required.
