Featuring one of the slimmest impact wrench designs in the industry, the Astro ONYX 1/2" Nano Impact Wrench is a supreme choice for working in tight spaces and with minimal room for maneuverability. This wrench displays the perfect balance of power (450 ft./lb. max torque) and low-profile construction (3.85”) to serve automotive professionals in transmission and engine environments, and beyond.

Full functionality

Despite a smaller design and compact construction, there’s no compromise on features and quality when it comes to the Astro ONYX 1/2" Nano Impact Wrench. The wrench features 6 total operating speeds (3 forward, 3 reverse), for exceptional control over the amount of torque delivered. A feathering trigger also offers variable speed capabilities to users, for slow-starting or burst tightening abilities.

Speed and directional adjustments are made simple with the flick of a switch, mounted on the rear of the wrench. Adjustments can be made on the fly, without having to use peripheral tools for the adjustment.

Powerful, yet quiet

Thanks to an innovative twin hammer design, this impact wrench offers high levels of torque at an impossibly low noise level of just 86 dB! This is perfect for working in compact spaces, where high range decibel noise can cause discomfort or temporary hearing loss.

Easy handling

For exceptional control at all times, users can rely on the ergonomic, molded-in grip of the Astro ONYX 1/2" Nano Impact Wrench. With raised finger separators and ample room for all hand sizes to position comfortably, it’s a universally formidable wrench!

With a weight of just 3lbs, there’s no user fatigue involved when using the wrench consistently throughout the day. This helps to expedite shop work and can improve the accuracy of work to avoid problems like stripped threads or over-torqued bolts.
