What it is
Washer FFD 22x9x6 for seismic applications C1 Fischer. Key specifications: internal diameter (mm) 9, external diameter (mm) 22.
A washer is a perforated disc placed under the nut or screw head to spread the load, prevent loosening or insulate the fixing.
What it is for
Used for anchoring to walls, ceilings and floors and for structural fixings, where the fixing is load-bearing and must be calculated.
How to use it
Choose an inner diameter matching the screw or threaded rod and a compatible material (zinc-plated, stainless steel, plastic). Place flat washers and penny washers under the nut to avoid damaging the substrate and to spread the pressure; place the spring washer under the nut, where it is flattened on tightening to resist vibration loosening. Use seismic washers only with the anchor they are certified for.
