HEICO-LOCK® Reaction Washers enable safe and convenient tightening of large bolted joints with commercially available electric, pneumatic and hydraulic torque tools – without requiring an additional reaction arm resp. other awkward mounts on the tool or component.

ADVANTAGES
– Easy and quick assembly – HEICO-LOCK® Reaction Washers are already glued in pairs
– Precise tightening due to low friction coefficient variation
– Reliable and permanent protection against self-loosening of the bolt or nut
– No need for additional reaction arms or mounts
– Prevention of accidents at work (e.g. pinching/crushing of the fingers, injuries caused by the tool slipping, etc.)
– No damage to adjacent surfaces caused by the reaction arm (e.g. damage to the anti-corrosive coating, deformations or breakages due to high contact forces)
– The tightening torque is applied axially – no harmful bending moments
– Dual sockets adapted to easily fit powered tools from most well-known tool manufacturers
