When a full-size impact wrench is too long for the work area, the AIRCAT 1077-TH 3/8" Stubby Impact Wrench gives technicians high torque output in a very short body. With 500 ft-lbs maximum torque and 700 ft-lbs of loosening torque, this compact impact is built for removing stubborn automotive, fleet, and shop fasteners where a larger tool may not fit. The 3/8" square drive works with common 3/8" impact sockets, while the 9,000 RPM free speed helps speed up fastener run-down once the nut or bolt is loose.
At only 3.85" long and 2.80 lbs., the 1077-TH is sized for tight engine bays, suspension work, underbody access, and compact machinery spaces. Its jumbo hammer mechanism (the internal impact system that delivers repeated striking force to the anvil) helps generate strong impact power while improving reliability. AIRCAT's patented Silencing Technology reduces the noise level to 89 dBA, and the trigger-mounted forward/reverse and power management switch allows one-hand directional and power control while the other hand positions the socket or steadies the workpiece.

- Very compact 3.85" body helps the tool fit into tight repair areas where a full-size impact wrench is difficult to position.
- Low weight aluminum alloy housing keeps the tool manageable during repeated service tasks.
- Reliable jumbo hammer mechanism delivers maximum power while increasing reliability.
- Patented Silencing Technology reduces the noise level to 89 dBA.
- Trigger-mounted combined forward/reverse and power management switch provides control and one-hand operation.
- 3/8" square drive supports common 3/8" impact sockets used in automotive and maintenance service work.
Applications:
- Automotive repair: Removing and installing fasteners around engines, brackets, suspension components, and underbody areas where tool clearance is limited.
- Fleet maintenance: Working on compact service areas, panels, guards, small chassis fasteners, and shop repair tasks where a short impact body improves access.
- General maintenance and MRO: Fastener run-down and removal on machinery covers, equipment frames, fixtures, and repair benches.
- Body shops and service bays: Handling smaller impact-fastening jobs where technicians need torque without the length of a conventional pistol-grip impact.
- DIY garage work: Useful for experienced home mechanics working on automotive projects, restoration jobs, and tight-access repairs with a properly sized air supply.
FAQs:
- Q: What makes the AIRCAT 1077-TH a stubby impact wrench?
A: The 1077-TH has a compact 3.85" body, making it much shorter than many standard pistol-grip impact wrenches. That shorter length helps technicians reach fasteners in tight engine, suspension, underbody, and equipment-service spaces. - Q: Can I use regular chrome sockets with this impact wrench?
A: No. Use impact-rated 3/8" drive sockets. Chrome hand sockets are not made for repeated impact loads and can crack or shatter when used with an air impact wrench. - Q: What size air hose should I use with the 1077-TH?
A: AIRCAT recommends a 3/8" air hose for this tool. A properly sized hose helps maintain airflow, which is important for preserving torque and speed during impact operation. - Q: Is 500 ft-lbs the same as loosening torque?
A: No. The 500 ft-lbs rating is the maximum torque figure, while the loosening torque is listed at 700 ft-lbs. Loosening torque refers to the breakaway force used to remove stuck or tightened fasteners. - Q: Is this tool suitable for lug nuts?
A: It may remove some automotive lug nuts when the fastener condition and torque requirement are within the tools capability, but final tightening should always be completed with a calibrated torque wrench. For frequent tire service or larger vehicles, a 1/2" drive impact wrench may be the better primary tool.
