Stahlwille Straight metric ring spanners, 6 x 7mm

Stahlwille 21 (StahlwilleSTABIL 21) is a straight double ended ring spanner range with no offset, in 18 metric sizes from 6 x 7 to 30 x 34mm. The ring spanners are made to DIN 837 / ISO 10103.

The bi-hex (double hexagon, 12-point) profile carries Stahlwille's AS-Drive (Anti-Slip Drive) form, which transmits high forces to the flats of nuts and bolts without damaging them. The spanners are Chrome Alloy Steel, chrome-plated. The spanners are forged in a die, hardened and quenched in an oil bath, with a double-T profile for bending strength and a round finish for grip. The ring sides are higher than on standard nuts, which rules out jamming.
