Overview
The DIN 431 low pipe nut with inch thread is a fastener with an inch pipe thread according to ISO 228-1.
Strength class DIN 431
DIN 431 nuts are made of steel of strength class 14H.
DIN 431 fastening group
DIN 431 nuts are divided into groups depending on their material of manufacture:
High-strength fasteners
Brass fasteners - nuts are made of brass
Stainless steel fasteners - nuts are made of stainless steel.
Materials for the manufacture of DIN 431 nuts
DIN 431 nuts are made of the following materials:
- Steel, which can optionally be coated with zinc. Zinc protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel grades A2 and A4. Steel grade allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.
- Brass. Brass nuts are used when the system is subjected to frequent dynamic, vibration and cyclic loads.
Areas of application for nuts according to DIN 431
Pipe nuts made using the technology of machine forming are actively used in various industries. They have become the most popular in mechanical engineering: such fasteners are used in the automotive industry, instrumentation, machine tool building, and the production of various equipment. It can also be used in construction to assemble metal frames and solve other problems.
