kwb 111819 Chave de caixa dupla de ponta 18 x 19 mm, aço cromo-vanádio, DIN 896

Reaching nuts on long threaded rods or recessed fasteners is difficult with a standard open-end spanner. The kwb 111819 tubular box spanner solves this by providing a deep, hollow shaft that slides over the rod and grips the nut securely. With two different hex sizes at each end, it covers common M12 and M12 fine thread applications without needing two separate tools.

Who is it for

This tubular box spanner is for mechanics, fitters, and maintenance technicians who regularly work with threaded rods, spark plugs, or recessed nuts. It is also useful for DIYers assembling furniture or working on bicycles where a standard spanner cannot reach.

Main features

• Double-ended design: 18 mm and 19 mm hex openings in one tool.
• Hollow shaft allows use on long threaded rods without bottoming out.
• Made from chrome vanadium steel, hardened for strength and chrome-plated for corrosion resistance.
• Complies with DIN 896 for tubular box spanners.
