The 1/2″ drive STW310 offers an extended 30Nm to 340Nm torque range, making it the ideal choice for heavier-duty applications including commercial vehicle maintenance, heavy plant equipment and high-capacity fastening tasks. This higher torque capacity provides the versatility needed for workshop environments handling diverse equipment from light assemblies through to substantial mechanical installations. The integrated digital angle mode delivers precise torque-plus-angle sequences without requiring separate measurement tools. Built to withstand rigorous workshop use, the STW310 features comprehensive alert systems including LED, vibration and audible indicators to confirm target torque achievement. The angle accumulation function proves particularly valuable when working with limited access or when specifications require multiple-turn angle measurements. Five user preset memories allow frequently-used torque values to be stored for instant recall, whilst the reversible 72-tooth Chrome Vanadium ratchet mechanism permits bi-directional torque measurement with read-outs in Nm, lb.in, lb.ft, kgf.m or degrees.
