About this product
The Faithfull 100mm Chrome Adjustable Spanner is the most compact size in the range, suited to tight spaces and confined areas where larger tools cannot reach. It is useful for lighter maintenance tasks, small machinery work, and compact tool kits or emergency kits, particularly when only a limited number of tools can be carried. It is made from chrome vanadium steel, forged, hardened and tempered, with a matt chrome-plated finish that resists corrosion. A knurled adjustment screw allows the jaws to be set precisely to fit various sizes of bolt and nut head. Jaw capacity is 15mm, with an overall length of 100mm (4in).
