Bulgarian-type washer RB-BUL Bossong

What it is

The Bossong RB-BUL Bulgarian-type washer is a professional solution for direct powder-actuated fastening in construction, designed to prevent plaster, coatings and panels from coming away from the substrate. Ideal for consolidation work on fragile surfaces, it ensures stability and even load distribution. Article code: RB-BUL.

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 strengthening masonry and concrete structures and for powder-actuated fastening into concrete and steel.

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.
