The socket adapter is an adapter with square drives of different sizes, which allows sockets of one size to be fitted on a ratchet of another.
What it is for
Used in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Fit it fully between ratchet and socket. When fitting a small socket on a large ratchet, avoid forcing, because the longer lever can damage the socket and the adapter.
