Overtightening or undertightening critical fasteners can lead to component failure, stripped threads, or unsafe assemblies a risk no professional workshop can afford. The Sealey STW902 is a micrometer-style torque wrench with a 3/8" square drive and a working range of 5-25Nm (3.7-18.5lb.ft), making it the right tool for precision fastening on lighter assemblies such as engine ancillaries, brake components, and trim fixings. The flip-reverse Chrome Vanadium steel ratchet head delivers smooth, reliable action in both directions, while the scale graduated in both Nm and lb.ft removes any need for unit conversion on the job. Each wrench is individually tested and supplied with its own numbered test certificate, calibrated to ±4% accuracy in accordance with BS EN ISO 6789-1:2017. The aluminium knurled handle ensures comfortable, controlled operation, and the wrench arrives in an EVA tray for protected storage. Backed by a lifetime guarantee, the STW902 is part of Sealey's Premier Hand Tools range, built for daily professional use.
