Combination Wrenches

Metric, imperial and the sizes you need

The metric range starts at 5.5 mm and covers the sizes most workshops reach for daily, with the long series set running from 8 mm through to 32 mm in one roll. If you work on older or imported gear, the 42AS range covers imperial sizes from ¼” up to 1”, and the thirteen-piece set spans that whole spread. For anything bigger again, the 45 heavy series picks up at 46 mm and goes to 80 mm.

Slim heads, more torque

The head thickness is cut back as far as it’ll go, which is what gets you into spaces a chunkier spanner won’t fit. You’d expect to give up some strength for that, but the torque figures are more than double what ISO 1711-1 asks for. The bright chrome-plated 42MP models add a polished finish and a tighter fit on the fastener, so there’s less chance of slipping.

Long, heavy and thin-open-end options

The 42LMP long series gives you extra leverage where access is awkward. The 42SLIM wrenches have thin open ends for shallow flats and tight clearances, and come as an eight-piece set covering 10 to 19 mm. The 45 heavy series is built for the big stuff.

Sets, wallets and storage

Sets come boxed or in roll-up wallets made from durable polyester. The 42MP/S17 covers 6 to 22 mm across seventeen pieces, the 42AS/13 does the same in imperial, and the eight-piece thin-open-end set rolls up small enough to live in a drawer. If you’re building yours up piece by piece, empty wallets and display supports are sold separately.
