More info

Like all Stahwille products, this open-ended spanner from their 10 Series is of the highest quality. Drop forged from high-grade chrome alloy steel, it has a chrome plated finish.

Undergoing a hardening process in the furnace, there is no scale build-up or decarbonisation. This spanner is then submerged in oil, making it a lifelong companion in your toolbox. Strong, yet lightweight due to Stahwille’s double-T profile, there is no chrome flaking even after years of use.


  • 12mm & 14mm double open-ended spanner
  • Lightweight for reduced hand and finger fatigue
  • Chrome plated for improved grip
  • 15° offset angle for improved purchase on fixings
  • Conforms to DIN 3110 and ISO 10102 Assembly Tools & Engineering
