Button Head Socket Screw ISO 7380

The button head socket screw ISO 7380 is manufactured in accordance with international quality standards. It has an equivalent — the German-made DIN 7380 screw. A variant with a button head and collar is also available.

The reliability of the fastener and the force with which it can be tightened are ensured by the hexagon socket recess. The screw is made of high-strength hardened steel with property class 10.9, stainless steel grade A2, and austenitic stainless steel grade A4. The use of these metals prevents rapid wear and extends the service life of the screw.

The choice of material depends on the operating conditions and field of application. For medical equipment, fasteners made of stainless steel grade A2 are more commonly used. Where anti-corrosion properties are important, preference is given to screws made of austenitic stainless steel. Under high loads, extreme temperatures, or aggressive environments, fasteners made of high-strength steel are used.
