Universal fastening element. The hammer-headed screw is twisted into the profile slot and so can mounted into an existing systems at a later date. The serrations break through the anodised film and creates a secure, electrical conductive connection.

Steel grade 8.8, black. Stainless steel A 2-70, bright. Drawing reference: L2 = approx. 2x thread pitch

The surface of the hexagon head bolt is polished and, with regard to design optimised for the use in hygienic environments. The bolt head is convex on the top face and the collar has a conical formed top surface. Instead of troublesome embossing or indentations, the bolt head is smooth with a surface finish of Ra 0.8 µm. Dirt and residue from products or cleaners seldom adheres and easy cleaning is ensured.

The Hygienic DESIGN fastening system was specially developed for use in food processing facilities. Special attention was paid to the cleaning-optimised geometry and a surface finish of Ra ≤ 0.8 µm. The quick and easy installation due to a pre-installed sealing washer rounds off the overall package.

EN ISO 7380-1 Form A: Hexagon socket button head screws. EN ISO 7380-2 Form B:Hexagon socket button head screws with collar.

Ideal elements for fastening cladding panels, Plexiglas covers etc. The oversized flange and the thread undercut ensure a stress-free, uniform force distribution on the respective surfaces. Projecting edges are kept to a minimum by the head height being kept as low as possible. An open-end spanner is used to screw the fastener in. The surface of the ball head screw is polished and, with regard to design optimised for the use in hygienic environments. The surface is polished to a surface finish of less than Ra 0.8 µm. Dirt and residue from products or cleaners seldom adheres and easy cleaning is ensured.

The wing nuts can be tightened and (generally) loosened tool-free. Drawing reference: DE = German style similar to DIN 315 AM = US style

When screwing the nuts onto the thread, the thread lock is plastically and elastically deformed. The elastic deformation causes a radial frictional lock against the nuts being loosened. The plastic thread lock is only effective when the nuts are fully screwed onto the male thread. The screw length must be selected so that at least two full threads protrude from the nut. Due to the plastic deformation of the thread lock, these nuts should only be used once.

Steel version: tempered to 900 N/mm², black oxidised. Stainless steel version: tempered to 900 N/mm², bright.

The surface of the cap nut is polished and, with regard to design optimised for the use in hygienic environments. The top of the nut is spherical and the collar has a conical formed top face. The nut has been designed as a low version so as to keep troublesome corners as few as possible. Due to the extremely high quality surface finish of much less than Ra 0.8 µm, hardly any dirt particles adhere to the surface.
