Washer NFE 27-619 M5 A4 hollow body

NFE 27-619 Hollow cone (rosette) washer is a fastener in the form of a thin-walled cone-shaped washer with a central hole. It has a “rosette” shape (cup-shaped, with a recess), which allows the head of a screw or bolt to be partially countersunk and ensures an aesthetically pleasing joint.

The hollow design reduces the product’s weight and ensures even load distribution across the material’s surface, preventing damage or deformation.

Applications: construction and installation; furniture industry; shipbuilding and marine industry; food and chemical industries; mechanical engineering.

Material: A4 stainless steel. A4 steel grade allows the fastener to be used in environments with significant temperature fluctuations and in aggressive and humid conditions. The KPD zinc-plated frame anchor with a double-threaded pin is a universal through-mount frame anchor designed for solid substrates—stone, concrete, and brick.
