Metal domed washer RB Bossong

What it is

The RB domed metal washer by Bossong is a galvanised steel component designed for building and mechanical applications. Its round shape with a central countersink ensures optimal load distribution, reducing the risk of damage to surfaces during fixing. Ideal for powder-actuated anchoring systems, this washer suits different screw or bolt diameters, ensuring stability and strength in structural and direct fixing settings.

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 powder-actuated fastening into concrete and steel 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.
