These are the all new screw dzus fasteners, and are an exclusive product to our company. These are absolutely ideal for fixing your panels where the fixing points are into timbers etc etc. you cannot use the normal dzus connection to go through wood therefore we have made an exact replica of the dzus fastener only it fixes using a screw so you simply use a screwdriver or drill to fix to a variety of materials and that's it! Never seen before and a truly new idea which is ownership to GLB Flight Products. We are the sole provider of these in the world and are truly great quality. Fasteners sold in packs of 6.
