A2 Stainless Fasteners

A2 stainless fasteners are a group of metal products made of A2 austenitic stainless steel.

A distinctive feature of this material is the presence of chromium and nickel in an optimal ratio. The chemical composition is designated as follows: X 5 CrNi 18-10 / X 4 CrNi 18-12.

Types of A2 fasteners

The catalogue offers a wide range of A2 stainless fasteners for various purposes. Products are selected based on the intended operating conditions:

• hex head bolts or wing bolts, with thread of various lengths;
• set screws (with countersunk, hex, or button head), for a slotted or cross-recess screwdriver;
• nuts and studs of various sizes and diameters;
• a full range of washers and retaining rings;
• cylindrical and conical pins;
• wire ropes with different numbers of strands and short-link chains;
• all types of self-tapping screws.

A2 stainless fasteners are used in virtually all branches of modern industry and manufacturing, except where acids, chlorine and seawater are present.

Advantages of A2 fasteners

Metalware made of A2 austenitic steel is not subject to hardening but retains its strength and other properties across a temperature range from -200°C to +425°C. It welds easily without becoming brittle. In addition:

• the absence of toxic impurities allows A2 fasteners to be used in equipment and devices for the food, medical and pharmaceutical industries;
• their non-magnetic property makes it possible to use A2 fasteners in instrument manufacturing;
• their appearance allows stainless steel products to be used in interior finishing as part of a design project.
