Locking rings
Many nutrunners and impact wrenches require a locking pin and a retaining ring to secure the tool.
Momento’s sockets and accessories therefore have a hole for the locking pin and a groove for the retaining ring.
The short time it takes to fit the locking pin and the retaining ring is a small price to pay for safe working conditions!
