When small fasteners sit behind brackets, covers, panels, and tight underhood components, the AIRCAT 811 1/4″ 30 Flex Head Ratchet gives technicians angled access in a compact pneumatic ratchet format. Its 35 ft-lbs maximum torque supports light-duty fastener removal and installation, while the 240 RPM free speed helps run small fasteners down faster than hand ratcheting. The 1/4″ square drive fits compatible 1/4″ drive sockets for work on small hardware, service covers, trim components, brackets, clamps, and close-clearance assemblies.The 811 uses a 3-position flex head design to help align the ratchet head with fasteners that are difficult to approach in a straight line. At 1.83 lbs. and 9.69″ long, it provides more reach than a mini palm ratchet while keeping the 1/4″ drive format manageable for small-fastener service. AIRCAT’s patented quiet tuned exhaust reduces sound output to 76 dBA, and the feather trigger helps the operator control speed during fastener start, run-down, and removal.Type: 30 Flex Head Ratchet | Model: 811 | Drive Size: 1/4″ Square Drive | Free Speed: 240 RPM | Bolt Capacity: 3/8″ | Max Torque: 35 ft-lbs @ 90 PSI | Weight: 1.83 lbs. | Length: 9.69″ | Air Consumption: 4.0 CFM | Recommended Hose Size: 3/8″ | Air Inlet: 1/4″ NPT | Noise Level: 76 dBAFeatures:Provides 35 ft-lbs of maximum torque for small fastener removal and installation.240 RPM free speed helps speed up run-down compared with manual ratcheting.1/4″ square drive fits compatible 1/4″ drive sockets for light hardware and close-access service work.3-position flex head design helps technicians approach fasteners from more than one angle.30 flex head layout supports improved access around brackets, covers, panels, and other tight service points.Ergonomically designed housing supports comfortable handling during repeated small-fastener tasks.Feather trigger gives the operator control over speed during fastener start, run-down, and removal.Patented quiet tuned exhaust reduces operating noise to 76 dBA.Applications:Automotive engine-bay service: Running down and removing small fasteners around brackets, covers, clamps, sensors, light accessory hardware, and tight underhood locations.Interior and trim work: Servicing small panel hardware, retainers, light brackets, and trim-area fasteners where angled access helps tool placement.Light equipment maintenance: Working on guards, access covers, compact service panels, and small mounting hardware that use 1/4″ drive sockets.Assembly and repair benches: Speeding up repetitive small-fastener installation before final hand feel or torque verification.MRO and shop maintenance: Handling small hardware on fixtures, housings, covers, and compact mechanical assemblies in general maintenance environments.FAQs:Q: What is the AIRCAT 811 best used for?A: The AIRCAT 811 is best used for small-fastener work where a 1/4″ drive pneumatic ratchet needs angled access. Common uses include automotive repair, light equipment service, interior and trim work, access cover removal, and general MRO tasks.Q: What is the benefit of the 30 flex head?A: The flex head helps position the socket on fasteners that are not easy to reach in a straight line. This is useful around brackets, panels, housings, and underhood components where tool clearance is limited.Q: How is the AIRCAT 811 different from the AIRCAT 800?A: The AIRCAT 800 is a standard 1/4″ composite ratchet with 320 RPM free speed. The AIRCAT 811 is a 1/4″ flex head ratchet with 240 RPM free speed and a 3-position flex head design for angled access.Q: What air hose size should I use with the AIRCAT 811?A: AIRCAT lists a 3/8″ recommended hose size and a 1/4″ NPT air inlet for this model. Using clean, regulated air helps the tool deliver proper speed and torque.Q: Can this ratchet replace a torque wrench?A: No. This pneumatic ratchet helps remove and run down small fasteners, but final torque should be checked with a calibrated torque wrench whenever a specific torque value is required.AVAILABLE VARIATIONS AND SPECIFICATIONS SKUFree Speed(RPM)Bolt Capacity(in.)Square Drive(in.)Max.
