BRONZEplus Striking Ring Wrench
BRONZEplus is a non-sparking striking ring wrench made from aluminium-bronze alloy for demanding assembly work in potentially explosive environments. It has a metric 12-point FlankTraction profile, a striking face and a design based on DIN 7444. The manufacturer specifies corrosion and wear resistance.
Main benefits
- non-sparking construction from non-ferrous aluminium-bronze alloy,
- 12-point FlankTraction profile for reliable force transfer,
- striking face for particularly demanding assembly work,
- explosion-protected according to the manufacturer,
- resistant to corrosion and wear,
- design based on DIN 7444.
Suitable applications
- maintenance and assembly in potentially explosive environments,
- chemical, petrochemical and gas industries,
- refineries, power generation and industrial plants,
- large bolted connections requiring a striking wrench.
Safety notice: suitability must be confirmed by the workplace risk assessment, applicable operating rules and the requirements of the specific explosive atmosphere.
How to select the correct size
The wrench size must match the across-flats dimension of the nut or bolt head. Before use, make sure the 12-point profile is fully seated and verify that the aluminium-bronze alloy and working method are suitable for the specific environment.
