Stud A4

The stainless steel grade used to manufacture A4 studs is designated 10Kh17N13M2 in domestic standards and AISI 316 abroad.

This fastener is a rod with threading that can be continuous or partial, applied on both ends. The lower section is intended for screwing into the materials being joined, the upper one — for a nut or another type of fastener.

The austenitic alloy of the A4 group contains molybdenum, which significantly improves such properties of the studs as:

• resistance to rust formation;
• non-magnetic;
• resistance to high and low temperatures;
• reliability and strength;
• environmental friendliness;
• ease of mechanical processing;
• stability on contact with aggressive substances, including acids, salts, chlorine, ammonia, and petroleum products.

Stainless studs A4 are used in many construction applications, in particular for installing hung ventilated and glazed façades. These fasteners are used in the chemical, food, medical, oil and gas, shipbuilding and other industries.
