Crowfoot Spanner Set 10-19mm 3/8in Drive Flare Nut CR-MO

A 10-piece crowfoot spanner set for tightening flare nuts and similar fittings where a standard spanner or socket will not reach easily. The open bi-hex adaptor design and stubby shape make it useful when access is restricted around pipework, unions and hard-to-reach connections.

Used with a 3/8in drive ratchet or torque wrench, these adaptors are suited to mechanical jobs where proper tightening matters but space is limited. They are commonly used for brake lines, fuel lines, air con fittings and other service work in garages, workshops and vehicle maintenance. For anyone dealing with awkward unions tucked behind components or close to surrounding parts, the open profile gives the clearance needed to work around the fitting.

The set includes sizes from 10mm to 19mm, covering a broad range of common flare nut and union sizes. Each adaptor is made from fully polished CR-MO and has a compact length of roughly 65mm to 70mm, helping reduce extra bulk when working in confined areas. The 3/8in drive fit keeps them straightforward to use with compatible drive tools, while the stubby pattern helps with access where a longer attachment would be awkward. As these adaptors add length to the wrench, torque setting adjustment is needed during use. Having the full size range together is handy for regular maintenance and helps avoid searching for the right size when awkward jobs come up.
