Washer with EPDM gasket R-EPDM Bossong. Key specifications: external diameter 16 mm, 19 mm, gasket material EPDM, washer material Stainless steel A2.
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 mechanical fixing of structures and components to walls, ceilings and floors, for roof maintenance and for sealing joints, gaps and service penetrations.
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.
