The Sealey STW309 is a professional-grade digital torque wrench featuring a 1/2″ square drive, designed for precise torque measurement in workshops and factory environments. This rugged tool combines digital accuracy with versatile functionality, making it suitable for automotive, plant maintenance, and engineering applications where precise fastener tightening is critical. The digital display provides clear LCD read-outs with LED indication, whilst audible alarms and vibration alerts notify the operator when target torque is achieved. The 180° flexi-head increases accessibility in confined spaces, allowing technicians to work effectively around obstructions. Measurements can be displayed in multiple units including Nm, lb.ft, lb.in, kgf.m or degrees, accommodating various technical specifications and international standards. A standout feature is the integrated angle mode, which eliminates the need for separate angle gauges or protractors when performing torque-plus-angle tightening sequences. The wrench accumulates angle measurements across multiple turns, particularly useful where limited access prevents continuous rotation. Users can select between track or peak modes and store up to five preset torque values in memory for frequently repeated tasks. The reversible Chrome Vanadium 72-tooth ratchet mechanism allows torque measurement in both directions, whilst maintaining accuracy to ±2% between 10% and 100% of the wrench’s stated capacity. The tool is supplied complete with a calibration test certificate and protective storage case, backed by a lifetime guarantee.
