What it is
The Fervi RN4034NA socket wrench adaptor is an accessory designed to join drive tools and sockets, transmitting torque in tightening and loosening operations. With a length of 36 mm and a weight of just 0.05 kg, it is a compact, lightweight element, ideal for work in tight spaces where easy handling is needed.
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 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.

- Mechanical engineering industry
- Mechanical workshops
