Description
The ST-IW4140 is a ½-inch square drive, gearless-type (direct-drive) angle impact wrench from Sonic, tailored for use in tight or restricted work-spaces such as engine bays, underneath lifts or within confined maintenance areas. It features a 90° (angle) head configuration which enables access in situations where a straight-gun wrench would be too bulky.
Features
:- Gearless (direct-drive) mechanism, eliminating reduction gears for more efficient power transfer and a more compact head.
- Angle (90°) head design, making it ideal for tight or awkward spaces where a straight tool cannot fit.
- High maximum torque (407 Nm) for a ½″ angle wrench, suitable for demanding fastening/loosening tasks.
- Compact body length (~248 mm) and moderate weight (~1.4 kg) which reduce operator fatigue and improve access.
- Ergonomic handle and design, likely includes features such as rubber grip, air-exhaust routing away from operator and workpiece (as is typical in similar models) though specific exhaust design details for this exact model may require checking manufacturer documentation.
- Fast free-speed (~6,500 rpm) enabling quicker run-down or break-free of fasteners compared to low-speed ratchet type tools.
- Industrial build-quality, suited for professional workshop or production use (automotive, maintenance, MRO).
- ½″ drive socket compatibility, enabling use of standard impact sockets and extensions.
- Angle head for improved ergonomics: easier to access bolt heads on undersides, inside frames, within vehicle wheel wells, etc.
Applications
:- Automotive service & repair: loosening/tightening wheel hubs, suspension mounts, engine bay bolts, under-chassis fasteners where conventional straight wrenches have clearance issues.
- Industrial maintenance: servicing heavy equipment, conveyors, presses, hoists where large bolts need removal/installation in confined machine bays or frames.
- Manufacturing production lines: where angle access is required for assembly of sub-frames, chassis, brackets, jigs where a straight tool cannot reach, and where throughput is important.
- Heavy-duty assembly or disassembly tasks: for example installation of large nuts or bolts (M16/M18 or similar) in vehicle or heavy machine assemblies.
- Agricultural, construction or off-road equipment servicing where access is obstructed and a compact, powerful angle impact tool is advantageous.
- Facilities maintenance (e.g., HVAC, plant machinery, heavy frames) where large fasteners exist in restricted access areas.
