Socket spanner insert for turning nuts has grip surface between each two adjacent slots with smaller spacing from longitudinal axis than slots themselves

摘要

The socket spanner insert has two opposite end sectors on the same longitudinal axis. The insertion aperture (100) running along the longitudinal axis is located in one of the end sectors of the socket spanner insert (10). The insertion aperture has several slots (12) at uniform spacing, running parallel to the longitudinal axis. There is a grip surface (11) with a groove (13) between each pair of adjacent slots, with a smaller spacing from the longitudinal axis that the slots themselves.
