Anti-Spark Offset Ring Wrench, suited to manual work for tightening and loosening threaded fasteners. Designed to work in potentially hazardous environments and made of a copper-beryllium alloy. Its structure makes it a useful tool for working on hard-to-reach, hidden and recessed nuts. It is ideal for working with precision and comfort while providing extra safety.

ALYCO's anti-spark range of tools is designed for use in environments where steel tools are not recommended because of their tendency to generate sparks that could cause fires or explosions. Tools made of non-ferrous materials reduce the risk of flammable sparks, as well as having a series of special anti-magnetic safety and corrosion-resistance characteristics.

The tools in this range are manufactured following international safety standards, in processes certified by the BAM and FM institutes, and comply with international standards for dimensions, cutting capacity and hardness.

Instructions for use: as they lack the hardness of conventional tools, they must be used with special care, particularly with regard to use and exposure temperature. They will only be replaced if they fail to reach the minimum hardness (Al-Br 30 HRC, Cu-Be 40 HRC). Tools containing more than 65% copper must not be used in contact with acetylene, due to their explosive potential.
