Stahlwille Long Series Combination Spanners. Metric, drop forged high-grade special steels and chrome plated. Manufactured to DIN 3113 form B/ISO 7738 form B. The spanners have been 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 Stahlwille\'s \'double-T profile\'. The unique plating method prevents the problem of chrome flaking. The ring end of the spanners are equipped with Anti-Slip Drive profile to permit high transmission of forces to the flats of the nuts and bolts without damaging them.
