About this product
The Faithfull 300mm (12in) Chrome Adjustable Spanner is a heavy-duty tool suited to industrial engineering, large plumbing installations, agricultural machinery maintenance and construction equipment work, where greater leverage and larger bolt sizes are involved. It is made from chrome vanadium steel, forged, hardened and tempered for durability, with a matt chrome-plated finish that resists corrosion.
A knurled adjustment screw allows the jaws, with a capacity of 35mm, to fit various bolt and nut head sizes with precision. It is a versatile general maintenance tool, particularly useful when only a limited number of tools can be carried or kept in a kit.
