The coating must not cause the thread dimensions to exceed the maximum material limit. For external threads (bolts), the coated thread must not exceed the or g tolerance position limit. For internal threads (nuts), it must not fall below the H or G position limit. Thickness Limitations The standard specifies how thick the coating should

A major component of the standard is specifying the thickness of the metallic coating. It ensures that the coating provides adequate corrosion protection without interfering with the mechanical functionality of the fastener, particularly the thread assembly. 3. Thread Tolerance Positions (9f, 6g, H, G) For external threads (bolts), the coated thread must

DIN 267 Part 9 (1979) stands as an important technical standard that established uniform requirements for electroplated coatings on mechanical fasteners. Its key contributions include:

The minimum thickness at specified measurement points on the fastener (typically on the head or flats, avoiding the threads where pooling occurs). 3. Hydrogen Embrittlement Protection

The DIN 267 Part 9 standard specifies the technical delivery conditions for fasteners with electroplated coatings. It provides crucial guidelines for manufacturers, engineers, and quality control professionals to ensure mechanical performance, corrosion protection, and dimensional accuracy after plating. 1.
