Stahlwille 13a/20 Imperial Combination Spanner Set, 20-Piece, 1/4" to 1 1/4"

Stahlwille 13a/20 is an imperial combination spanner set of 20 pieces from 1/4" to 1 1/4" across flats. Each spanner has the same size at both ends: an open end with the jaw angled at 15° and a 12-point ring offset by 15°.

The set contains the 1/4", 9/32", 5/16", 11/32", 3/8", 7/16", 1/2", 9/16", 19/32", 5/8", 11/16", 3/4", 25/32", 13/16", 7/8", 15/16", 1", 1 1/16", 1 1/8" and 1 1/4" spanners. They are the individually sold Stahlwille 13a spanners, so a worn or missing size can be replaced from the range. Set weight is 3,180 g. The ring has the Stahlwille Anti-Slip-Drive (AS-Drive) profile, which puts the force on the flanks of the bolt or nut rather than the corners. The spanners are Chrome Alloy Steel, chrome-plated. The spanners are drop-forged, hardened and cooled in an oil bath, with a double-T profile for bending strength, a round finish for grip, thin-walled rings for hard-to-reach fastening points and a reinforced transition from jaw to shaft, where the highest forces act (Offset Shaft Design).
