The cap nut DIN 1587 is used as a decorative element, which is a closed part of the fastener. At the same time, it additionally protects the thread from mechanical damage and corrosion, prevents injuries in contact with the fastener, and gives the product an aesthetic appearance.
Strength class DIN 1587
DIN 1587 nuts are made of steel of strength classes 5 and 6.
Fastening group DIN 1587
Most of these nuts are made of stainless steel and belong to the stainless steel fastener group.
Materials of manufacture
DIN 1587 is available in a variety of materials:
- Steel
- Polyamide
- Chrome
- Stainless steel A1, A2, A4
Scope of application of the DIN 1587 cap nut
Most often, this fastener is used for the aesthetic appearance of the structure. They are widely used in mechanical engineering and instrumentation.
The scope of application also directly depends on the material of manufacture and coating of the product:
- The zinc coating on steel protects against corrosion if the fastener is to be used in aggressive environments.
- Brass nuts are used if the system is subjected to frequent dynamic, vibration, and cyclic loads.
- The polyamide bolt withstands mechanical shocks, does not crack or break at the permissible load factor.
- Stainless steel allows the use of nuts at significant temperature changes and in aggressive and humid environments.
