Overview

Weighing just 302 grams, the VESSEL 400ER3 sits in the range of a handheld manual impact tool rather than a powered driver, consistent with Vessel's known lineup of hand impact drivers.

At under 302 grams, this sits closer to a hand tool than a powered impact driver, which typically weighs several times more. No power source, bit type, or torque figures are listed, so confirm those against the source listing if precision matters for your use.

Who it's for

Fits anyone dealing with stuck, corroded, or stripped screws that a standard screwdriver cannot budge, where a manual impact driver's hammer action helps break the fastener loose. Not built as a substitute for a powered impact driver on repetitive fastening work.

Performance notes

The 302 gram weight points to a manual, hand operated impact tool rather than a battery powered one, relying on a struck hammer blow to convert force into turning torque on stuck fasteners.
