Stainless steel is characterized by a proportion of more than 10.5% chromium and a maximum of 1.2% carbon[10][11], which must be dissolved in the austenitic or ferritic solid solution. This high chromium content creates a protective and dense passive layer of chromium oxide on the material surface.

The term plain indicates a completely untreated, merely oiled, smooth surface for all DIN and ISO screws such as wood screws, hexagon head screws, threaded rods, nuts and many types of washers.

In materials science, the term ‘aluminium’ refers to all materials based on the element aluminium. The material 3.3535, also known as DIN EN AW 5754 or AlMg3, belongs to the group of aluminium-magnesium alloys. The material is classified as non-hardening and is therefore naturally hard. In the H111 condition, it can be characterised as having average dimensional stability.
