The Stanley FatMax FMMT13037-0 is a 14mm combination wrench with an open jaw and a 12-point ring end. The anti-slip jaw treatment gives better purchase on fastener flats compared to a standard polished open end, which is particularly useful at this size where the torque loads start to increase noticeably.

14mm fasteners appear on heavier mechanical assemblies, structural connections, and some plumbing fittings. M10 bolts with flanged heads and certain compression fittings use a 14mm hex. The combination format gives you flexibility on site: ring end for full engagement on accessible fasteners, open end for reaching fixings in confined spaces or along pipe runs where overhead clearance is restricted.

Chrome vanadium steel construction handles the higher torque demands of this size without deformation. The 12-point ring engages in 30-degree increments, so you can reposition and turn even where there is limited space to swing the wrench. At 98g it remains a manageable weight for carrying in a spanner roll alongside the rest of the set.
