ZAW-410B 3/8-Inch Air Wrench – Professional Two Hammer Pneumatic Impact Wrench with Side Exhaust
The ZAW-410B 3/8-inch air wrench delivers professional-grade performance in a lightweight, compact form, making it ideal for technicians who need consistent torque, durability, and maneuverability. Built with a two hammer impact mechanism, this pneumatic wrench provides strong, balanced impacts for smooth operation and long-lasting reliability — perfect for automotive repair, machinery maintenance, and general assembly work.
Compact Power for Everyday Use
With its 3/8-inch drive size, the ZAW-410B is designed for medium-duty applications, offering enough torque to remove stubborn fasteners without overwhelming delicate parts. The two hammer system ensures even torque delivery, reduces vibration, and protects the tool’s internal components.
Durable and Workshop-Ready
Manufactured with a high-strength alloy housing and heat-treated internal parts, this impact wrench is engineered to withstand daily use in demanding environments. It’s a dependable choice for both professional workshops and industrial assembly lines.
Side Exhaust for Cleaner Operation
The side exhaust system channels air away from the work surface, helping to keep dust and debris under control while preventing air from blowing directly toward the operator. This makes the ZAW-410B safer and cleaner to use, especially in sensitive or confined areas.
