Screw cylindrical head - hex DIN 912 M3x12 stainless steel A4

Product detailed description

The hexagon socket head cap screw according to DIN 912, ISO 4762 and ČSN 021143, with dimensions M3 x 12 mm, is made of stainless steel grade A4-70. This screw is intended for fixed screw connections that require high preload, making it an ideal choice for applications where high resistance to corrosion and mechanical stress is required.

The A4-70 material is an austenitic stainless steel that offers excellent corrosion resistance, making it suitable for use in aggressive environments such as the chemical industry or marine applications. Strength class 70 indicates a minimum yield strength of 700 MPa, which guarantees high mechanical resistance and reliability in demanding conditions.

The cylindrical head of the screw is designed for use with an Allen key, which allows for efficient torque transmission during assembly and disassembly. The internal hexagon ensures precise tool retention, minimizing the risk of head damage during handling.

This screw is suitable for a wide range of applications, including the mechanical engineering industry, equipment manufacturing and construction, where high reliability and resistance to external influences are required. Its use is particularly advantageous where it is necessary to ensure long-term service life and minimal maintenance of joints.
