Melco TM19 Metric Box Spanner 20 x 21mm x 125mm (5in) TM19

The Melco TM19 Box Spanner features 20mm x 21mm sizing with a 125mm length, providing closely-matched apertures for installations where these sequential sizes appear together. This configuration is commonly required for specific automotive models and plumbing systems where 20mm and 21mm represent standard fastener dimensions. Manufactured from bright plated steel, this spanner delivers dependable performance whilst the 125mm length offers practical reach for most applications. The tubular construction accesses recessed fasteners typical of radiator installations, brake assemblies, and suspension components. The narrow spread between 20mm and 21mm makes this particularly efficient for work on equipment standardised to these dimensions. Having both sizes on a double-ended tool eliminates the need to switch between separate spanners during sequential fastening operations. Tommy bar provision enables proper tightening torque and the breaking force needed for corroded or seized fixings.
