When deep-set large fasteners require both 3/4" drive strength and extra socket reach, the AIRCAT 1680-A-6 3/4" Impact Wrench with 6" Anvil gives maintenance teams a long-anvil pneumatic tool for heavy vehicle, agricultural, fleet, and industrial service work. Its 1,400 ft-lbs maximum torque supports large bolt removal and installation on frames, equipment mounts, suspension components, wheel-area hardware, and machinery assemblies, while 1,600 ft-lbs of loosening torque helps break tight or corroded fasteners free before run-down. The 3/4" x 6" square drive helps position sockets onto recessed hardware where a standard-anvil impact wrench may not reach far enough.
The 1680-A-6 uses a durable hard-hitting twin hammer mechanism (an impact design that delivers two balanced blows per rotation for steady torque transfer), making it a practical choice for repeated high-load fastening work. Triple heat treated Ni-Cr-Mo alloy steel hammer mechanism components help support reliability under impact loads, while AIRCAT's patented Silencing Technology reduces noise to 89 dBA. At 14.80 lbs. and 14.80" long, this 6" anvil model is built for access-focused large-fastener work where added reach is essential.

- 6" anvil helps reach recessed wheel hardware, deep fastener locations, frame components, and equipment service points.
- Durable hard-hitting twin hammer mechanism supports strong impact output for repeated 3/4" drive service work.
- Patented Silencing Technology reduces operating noise to 89 dBA.
- Patented AIRCAT grip supports controlled handling during large-fastener removal, installation, and direction changes.
- Combined power management forward/reverse switch gives the operator direction and output control from the tool body.
- Triple heat treated Ni-Cr-Mo alloy steel hammer mechanism helps support reliability under repeated impact loads.
- Combined through-hole and friction-ring socket retainer helps secure compatible 3/4" drive impact sockets.
Applications:
- Fleet and truck maintenance: Removing and installing chassis fasteners, suspension hardware, frame brackets, mounts, guards, and large service bolts where extended anvil reach helps socket placement.
- Agricultural equipment service: Working on tractors, implements, service vehicles, frames, guards, mounts, and large-bolt assemblies that require 3/4" drive sockets.
- Industrial maintenance and MRO: Running down and removing large fasteners on machinery frames, access plates, equipment bases, fixtures, and plant repair assemblies.
- Bus and large vehicle repair: Servicing underbody components, drivetrain supports, suspension assemblies, and deep fastener locations that call for 3/4" impact capability.
- Heavy equipment repair: Supporting service work on loaders, lifts, construction equipment, shop machinery, and support equipment where a 1/2" impact wrench may be underpowered.
FAQs:
- Q: What is the AIRCAT 1680-A-6 best used for?
A: The AIRCAT 1680-A-6 is best used for 3/4" drive fastening where large bolts require high torque and extra reach. Common uses include fleet maintenance, agricultural equipment service, large vehicle repair, heavy equipment work, and industrial MRO. - Q: What is the benefit of the 6" anvil?
A: The 6" anvil moves the socket farther away from the tool body, making it easier to reach deep or recessed fasteners. This is useful around wheels, frames, guards, brackets, and equipment components where a standard-anvil impact wrench may not provide enough access. - Q: What is the difference between maximum torque and loosening torque?
A: Maximum torque is the tool's headline output rating, while loosening torque is the breakaway force used to remove tightened or stuck fasteners. AIRCAT lists this model at 1,400 ft-lbs maximum torque and 1,600 ft-lbs loosening torque. - Q: What air hose size should I use with the AIRCAT 1680-A-6?
A: AIRCAT lists a 1/2" recommended hose size and a 3/8" NPT air inlet for this model. Using the recommended hose size helps maintain airflow so the tool can deliver proper torque and speed under load. - Q: Can I use 1/2" drive sockets with this impact wrench?
A: No. The 1680-A-6 has a 3/4" square drive and should be used with compatible 3/4" drive impact-rated sockets. Do not use chrome hand sockets or undersized drive adapters for high-torque impact work.
