Three groups, one system
The range is organised in three groups: screws by head shape, nuts and washers. In a grating or fence fastening all three are specified together — the head shape follows the application, the nut follows the bolt, the washer distributes the clamping force.
Choose the material in pairs
A hot-dip galvanized bolt needs a nut whose thread has been tapped oversize to take the zinc layer, so hot-dip belongs with hot-dip. Stainless goes with stainless. Geomet is the choice where the coating must not change a dimension — in a hexagon socket, for example.
Where they are used
These fasteners are the screw part of the grating fastenings and the fence fastenings. Drawings for dimensions outside the range go to custom manufacturing.
Frequently asked questions
Which standards do ARNELL fasteners comply with?
Screws, nuts and washers to common DIN/ISO standards, including countersunk screws DIN 7991 / ISO 10642, cylinder screws DIN 912 / ISO 4762 and DIN 84 / ISO 1207, and washers DIN 125 / ISO 7089.
What does property class 8.8 mean?
It describes the strength of steel screws: 800 N/mm² tensile strength at 80 % yield strength - a common standard for load-bearing connections.
Which surface finishes are available for the fasteners?
Among others hot-dip galvanized and Geomet-coated for durable corrosion protection.
