The bolt corrosion-proof DIN931 M6х70 A2 CR is the metal fixtures used in a life, at production, in the industry. Among all types of fasteners, the most widely used are such as bolts, screws and rods. The most widespread and reliable element of fastening of products is a bolt - hardware in the form of a hairpin with a carving and, as a rule, with a hexagonal head. By type of threading, there are: models with partial thread (applicable for connecting several parts) and with full thread (the most common and universal model).
Screws are used for more specialized fastening purposes. Screws are a metal rod with a slot (or a head with a slot), such fasteners are usually used to attach the part to the surface. In addition to the main dimensions, the screws differ in the type of heads with slots.
The range of the store has not only the most common types of bolts - bolts with metric thread (hexagon head, square head, square head, furniture, ring, structural), but also rarer subspecies - models with hexagon head and inch thread.
The most popular due to their properties are stainless steel products A2 and A4.
Steel A2 - (American analogue of AISI 304) the most common type of austenitic stainless steel. steel in metal products.
Products made of such steel have good corrosion resistance in clean water and air, are non-toxic, non-hardenable, easy to weld and do not become brittle.
Are applied in different industries where there are a number of requirements to hardware which are specified above.
Fasteners made of stainless steel A2 are not suitable for use in acids and chlorine-containing media.
Steel A4 - (American analogue of AISI 316) is very similar in its properties and composition to stainless steel A2, the main difference is the addition of 2-3% molybdenum.
Due to molybdenum, such stainless steel significantly increases the resistance to corrosion in acidic and other aggressive environments, so it is still often called "acid-resistant steel".
Accordingly, fasteners and rigging made of A4 steel are widely used in shipbuilding and other industries where metal products require good resistance to acid and other aggressive environments.
