Hex Bit Socket Set 4-19mm 1/2in Drive 9pc Metric Allen Key

A 1/2in drive hex bit socket set for working on metric Allen fixings across a wide size range. It covers common hex socket sizes from H4 to H19mm, making it a useful option for garage, workshop and general repair work where standard Allen keys are not practical.

Used for loosening and tightening internal hex fasteners with a ratchet or breaker bar, this type of hex drive socket set suits vehicle maintenance, machinery work, workshop servicing and DIY repairs. It is especially handy when dealing with larger or tighter fasteners where more leverage is needed than a loose Allen key can comfortably give. For regular maintenance jobs, having several metric hex bit sockets together helps keep the right size close to hand.

The hex bit set is based around a 1/2in square drive, so it works with common ratchets and related drive tools already used in many garages and workshops. The supplied size range starts at H4mm and goes up to H19mm, covering smaller fittings as well as larger hex fasteners often found on mechanical assemblies and equipment. Keeping these Allen key bits grouped in one set also makes it easier to stay organised during repeated servicing or fitting work, so you are not searching for individual sizes as jobs change.
