Hex Key Set 4mm 5mm Long Reach Ball End 225mm S2 Steel

A 2-piece hex key set covering 4mm and 5mm sizes, made for reaching recessed or awkwardly placed hex fixings. With 225mm long shafts, ball end tips and S2 steel construction, these Allen keys are a practical choice when standard short keys do not give enough access.

Used for maintenance, fitting and repair work where socket head screws sit behind pipework, casings or other obstructions, this hex set is especially useful for central heating pump work. The ball end design helps when you need to approach a fastener at an angle, which can make workshop jobs, servicing tasks and home maintenance work more straightforward when access is limited.

The supplied size combination covers two common hex sizes for this type of work, while the long reach pattern helps get further into narrow spaces without needing extra extensions or adaptors. S2 steel is widely used for tool applications where strength and repeated use matter, making these keys suitable for regular garage or workshop use. For anyone dealing with awkward access points, the longer shafts and angled entry of the ball end tips help reduce the need to keep swapping tools or repositioning the job repeatedly.
