Hex Key Set 31pc Metric Imperial AF Long & Short Allen Keys

A 31-piece hex key set covering both metric and imperial AF sizes for a wide range of fastening jobs. Supplied with long and short Allen keys, it gives you the common sizes needed for routine workshop, garage and household repairs.

Used for tightening and loosening hex socket screws on bikes, machinery, vehicles, furniture, tools and general fittings, this hex set suits both trade and DIY use. The mix of metric and imperial sizes is handy when working on older equipment, imported items or mixed fasteners, helping you deal with servicing, assembly and maintenance work without hunting for separate keys.

The set includes 15 metric sizes from 0.7mm up to 10mm and 15 imperial AF sizes from 0.028in up to 3/8in. Having both long and short pattern keys makes it easier to choose what suits the job, whether you need a bit more reach into recessed fixings or a more compact key where space is tight. The broad size spread covers many common fasteners used in regular repair and fitting work, which helps keep the right key close to hand when jobs come up. Kept in a toolbox, garage drawer or van, it is a practical set for repeated day-to-day use.
