Overview
The ACDelco ANI405 is an impact tool weighing about 5.72 pounds, listed under ACDelco's tools line rather than its more familiar automotive parts catalog.
Impact tools deliver rotational force in rapid bursts rather than steady turning force, which is what lets them break loose stuck lug nuts and rusted bolts that a standard wrench struggles with. At 5.72 pounds it sits in the weight range typical of a handheld impact wrench rather than a larger stationary tool.

Strengths and trade-offs
Drawn from this product's published specifications.
- Built for high torque fastener work
- Solid buyer rating across a sizable review count
- Power source and torque rating not listed
- Heavier to hold than a standard wrench
Performance notes
Impact mechanisms store energy and release it in short rotational bursts, which lets them free fasteners that resist steady turning force, and the weight here fits a tool meant to be held and aimed rather than mounted.
