During a precision tapping job, an operator notices the tap slipping within the wrench. Which corrective action should be taken to resolve this using an adjustable tap wrench?
Retighten the jaws to secure the tap firmly in the wrench
An adjustable tap wrench works by clamping the square shank of the tap between two jaws, and it can only drive the tap if that grip is firm. When the tap slips, the grip is the thing to examine.
The jaws are closed onto the square by turning the handle; the tighter they close, the more securely the square is held.
If the tap turns inside the wrench without cutting, it means the jaws have not clamped the square hard enough and are letting it spin.
The correct corrective action, and the very reason the wrench is adjustable, is to retighten the jaws so they grip the square shank firmly.
Applying greater force to a slipping tap risks snapping it, switching to a fixed wrench is unnecessary and may not fit the shank, and the tap itself is not faulty, so replacing it solves nothing.
Restoring a firm clamp on the shank is what lets the wrench drive the tap again.
Hence, the answer is Retighten the jaws to secure the tap firmly in the wrench.
