Overview

The AEROPRO A398 is an impact tool weighing 5.3 pounds, listed under the Impacts category for driving and removing stubborn fasteners. Beyond title and weight, the source data does not include torque, drive size or power source figures.

Impact tools work by delivering rotational hammering blows that break loose fasteners a plain wrench or driver cannot budge. Without a listed torque rating or drive size for the A398, its exact fastener range is not something this data can confirm either way.

  • Weighs 5.3 pounds
  • Listed under Tools > Impacts
  • Model A398 from AeroPro
  • No torque or drive size disclosed

Who it's for

Could suit anyone needing an impact tool for fastener work, but buyers should confirm drive size and torque directly before ordering since neither is listed here.

Pros and cons

Pros
  • Weight suggests a full-size tool rather than a compact driver
Cons
  • Torque, drive size and power source are not listed
  • 5.3 pound weight may tire the wrist in extended one-handed use

Performance notes

At 5.3 pounds the A398 has the heft of a full-size impact tool rather than a compact driver, which typically means more leverage but less one-handed maneuverability. Torque output and power source are not part of the available spec, so real-world fastening capability cannot be sized up from this data alone.
