What it is
The X3 Bossong washer (code: Rondella X3) is a professional solution for building fixings that require strength and even load distribution. Designed to be paired with threaded rods and nuts, it is aimed at building contractors, engineering practices and infrastructure operators looking for reliable components for structural and non-structural anchoring.
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 assembling steel structures and for mechanical fixing of structures and components to walls, ceilings and floors.
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.
