Stahlwille Double open-end wrench

Conventional Wrenches

The strongest stresses occur at the junction between the jaw and the handle when tightening screws. This aspect is rarely considered in standard wrenches. In tough conditions, this can lead to tool breakage and serious hand injuries.

STAHLWILLE Wrenches

To reduce the risk of breakage, we concentrate material where stresses occur and remove it where it is not needed. This results in extremely stable yet slim and lightweight tools that allow work even in the tightest spaces due to their compact dimensions.

Extremely Durable, Exceptionally Long-Lasting

• Forged from high-quality special steels in a die.
• Optimal hardening in a continuous furnace without scaling and surface decarburization.
• Gentle quenching in an oil bath.

Light and Ergonomic

• High bending strength and low weight due to the STAHLWILLE typical double-T profile.
• Grippy, skin-friendly surface thanks to the STAHLWILLE round finish.

Key Advantages for Tightening and Loosening Screws

• Stronger than any screw thanks to the forged double hex.
• Thinner than standard rings – allowing work in the tightest spots.
• Taller than standardized nuts – preventing the wrench from getting stuck.

Quality Assured

The STAHLWILLE Quality Assurance System has received the internationally recognized certificate according to DIN ISO 9001 from DQS.
