Abstract

The spanner for threaded fasteners has a shaft (3) with a drive head (30) at one end to receive the fastener. The inner face of the drive head has projections extending inwardly from its upper edge. When the spanner is placed on a fastener the projections engage the fastener to stabilise the spanner.
