Stainless Steel Screws Bolts Nuts Washers Rivets Threaded Rod And More
In order to ensure the quality of every stainless steel item stocked in our warehouse and within our catalogue at bolts nuts screws Australia, each stainless steel fastener or item is manufactured to specific grades set by various countries and organizations; within our range, you will find various AS standards assigned to products and or Din numbers. Notably, besides the AS number or the Din Number, there is always a specific grade of stainless steel assigned to each fastener. These are most commonly Grades 304 and 316, also known as A2 and A4. For instance, any of the stainless steel bolts or socket screws stocked in our warehouse must have A2 or A4 stamped on the head. This is a minimum requirement and indicates its level of protection against corrosion. The Din and the AS specify the dimensions, such as thread length and spanner size. Here is an example of a Din Number and an As Number, including what they mean and where they come from.
The industry standard for our imperial UNC hex bolts stocked in our warehouse is ANSI B18.2.1, which was set by the American National Standards Institute (ANSI) in collaboration with the American Society of Mechanical Engineers (ASME). These organizations work together to establish standards for various products, including dimensional specifications for hex bolts and screws.
The specification for Metric stainless steel hex bolts stocked at Bolts Nuts Screws is DIN 931, set by the Deutsches Institut für Normung (DIN), the German Institute for Standardization. DIN standards are widely used in engineering and manufacturing, particularly in Europe.
Both ANSI B18.2.1 and DIN 931 are recognized as important standards in their respective regions and are used globally to ensure consistency in manufacturing and quality.
So that part ensures the dimensions, Then we look at the same identical looking product wheather it be a rivet or bolt and nut screw for outdoors, countersunk bolts self tapper, split pin tee nut and hardware for instance Dee shackles and turnbuckles and very importantly define the grade of the stainless steel.
Our two most common types sold from our website and store are A2/70 Grade 304 stainless steel and A4/70 Grade 316 Stainless steel. Here is an explanation of the grades who set them and what they tell us.
The standards for Grade 304 (A2) and Grade 316 (A4) stainless steel are primarily set by several international organizations:
-
International Organization for Standardization (ISO):
- ISO is responsible for the A2 and A4 designations in stainless steel grades. Specifically, ISO 3506 is the standard that defines the mechanical properties of corrosion-resistant stainless steel fasteners, with A2 corresponding to 304 stainless steel and A4 corresponding to 316 stainless steel.
-
American Society for Testing and Materials (ASTM):
- ASTM sets the standards for stainless steel in the United States, including its composition, mechanical properties, and other characteristics. For example, ASTM A240 and ASTM A276 are standards that cover the requirements for 304 and 316 stainless steel.
-
Deutsches Institut für Normung (DIN):
- DIN also defines standards for stainless steel, particularly in Europe. DIN EN ISO 3506, which aligns with the ISO standards, specifies the properties for A2 (304) and A4 (316) stainless steels.
These standards are widely recognized and adopted globally to ensure consistency in the quality and properties of stainless steel products.
