Stahlwille Series 13A Combination Spanners. AF Imperial, with 15° offset ring end. Drop forged from high-grade chrome alloy steel and chrome plated. 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 Stahlwille\'s \'double-T profile\'. Stahlwille\'s unique plating method prevents the problem of chrome flaking. The spanner\'s ring ends are equipped with an Anti-Slip Drive profile to permit high transmission of forces to the flats of the nuts and bolts without damaging them.
