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.
