Stahlwille Series 13 Combination Spanners. Metric sizes, with 15° offset ring end. They are drop forged from high-grade chrome alloy steel and chrome plated. Manufactured to DIN 3113 form A/ISO 7738 form A. The spanners are optimally hardened in continuous furnaces with no scale build-up or skin decarburisation and gently quenched in oil. They are extremely strong yet lightweight due to Stahlwilles\'s \'double-T profile\'. Stahlwille\'s unique plating method prevents the problem of chrome flaking. The ring end of the spanners are equipped with an Anti-Slip Drive profile. This permits high transmission of forces to the flats of the nuts and bolts without damaging them.MADE IN GERMANY.Stahlwille Combination Spanner. Size: 22mm.Length: 260mm.
