What it is
Double curved bi-hex spanners, art. 90. Key specifications: type double offset ring spanner, finish matt chrome-plated.
Hand tightening tools are spanners, sockets, screwdrivers and hex keys for tightening and loosening screws and nuts in workshops, maintenance and assembly.
What it is for
Used in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Choose a tool of the exact size and profile of the screw or nut, so the force is transferred to the recess without damaging it. Keep the tool in line and tighten with progressive force, using a torque wrench where a precise torque is required. On live parts, work only with 1000 V insulated tools and, whenever possible, after switching off the power.
