The PN 82281 standard defines metric screws with a cylindrical head and a straight slotted head. The screw head has a diameter that ranges from 5 mm to 10 mm, depending on the thread size M3, M4 or M5. The threads on DIN 920 screws are manufactured according to the metric standard ISO 68-1, and their parameters, such as pitch size, thread diameter, and thread length, meet the requirements of this standard. DIN 920 screws are made of various materials such as steel, stainless steel or brass, depending on the application and operating conditions.
Strength class PN 82281
PN 82281 screws are made of steel of strength class 4.8.
Fastening group PN 82281
Screws PN 82281 belong to the stainless steel fasteners group.
Materials used for manufacturing PN 82281 screws
PN 82281 screws are made of the following materials:
- Steel, strength class 4.8, which can be additionally coated with zinc. Zinc (Plated) protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel. Steel grade A2 allows the bolts to be used at significant temperature changes and in aggressive and humid environments.
Application range of PN 82281 screws
PN 82281 screws are commonly used in mechanical and electrical engineering, as well as in other industries that require reliable connection of parts with the possibility of quick disassembly. These screws provide a stable connection, which allows them to be used in various operating conditions, including high loads and different temperature conditions. Applications for PN 82281 screws include the connection of mechanical components, for example, in the manufacture of machinery, industrial equipment, production lines, as well as in the manufacture of various devices that require reliable connection of parts, for example, in the manufacture of electronics, equipment and other devices. In addition, PN 82281 screws can be used in repair work and other situations where quick connection and disassembly of parts is required without the need to use tools with special nozzles.
Thus, DIN 920 is a fairly universal standard that is widely used in various industries.
