Overview
The Astro 1834 is listed at just 0.22 pounds, the only spec Astro provides. That weight places it as a compact impact accessory rather than a full impact wrench.
Astro's own impact wrenches typically weigh well over a pound, so a 0.22 pound listing for the 1834 points toward a bit, socket or small attachment meant to pair with an impact driver or wrench rather than a stand-alone tool. The spec sheet does not list dimensions, drive size or material, so buyers should check the product photos to confirm exact fitment before ordering.
- 0.22 pound weight
- Astro brand
- Impact category accessory
- Compact size
Who it's for
Likely useful to anyone already running an impact driver or wrench who needs a specific attachment. Not a fit for someone shopping for a complete impact wrench.
Pros and cons
- Very light at 0.22 pounds
- Compact enough to carry as a spare attachment
- No drive size, material or dimensions listed
- Not a stand-alone impact wrench
Performance notes
With only weight given and no drive size or material listed, performance claims are limited. The light weight suggests it is designed to be driven by a separate impact tool rather than to generate its own striking force.
