Metal flat washer R Bossong

What it is

The R flat metal washer by Bossong is a steel component designed for fixing and mechanical assembly applications in building. Made to ensure even load distribution and prevent damage to surfaces, this washer suits different anchoring and fastener systems. The variety of diameters and thicknesses available makes it suitable for residential, industrial and infrastructure settings, where precision and strength are essential requirements.

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.
