At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to DIN 267. DIN 267 – Fasteners; technical delivery conditions. A historic multi-part German umbrella standard defining general requirements for threaded fasteners: property/strength classes, tolerances, surface finishes and coatings, acceptance and marking. Its mechanical-property parts have largely been superseded by ISO 898 (steel) and ISO 3506 (stainless); coating/finish parts remain in use.

| Grade / Class | UNS / Designation | Type / Notes |
|---|---|---|
| Property classes (bolts) | DIN 267-3 (superseded by ISO 898-1) | e.g. 4.6, 5.6, 8.8, 10.9, 12.9 |
| Property classes (nuts) | DIN 267-4 (superseded by ISO 898-2) | e.g. 5, 6, 8, 10, 12 |
| Part 10 hot-dip galvanized | DIN 267-10 | Coating technical delivery conditions |

Minimum mechanical requirements per DIN 267.
| Grade / Class / Condition | Tensile Strength, min | Yield Strength, min | Elongation, min % | Hardness |
|---|---|---|---|---|
| Class 8.8 | 116 (800) | 94 (640) | 12 | 255-336 HV |
| Class 10.9 | 145 (1000) | 131 (900) | 9 | 320-380 HV |
| Class 12.9 | 174 (1200) | 157 (1080) | 8 | 385-435 HV |
| Grade | Key Composition, % |

| 8.8 / 10.9 | C / C-boron / alloy steel, quenched & tempered per ISO 898-1 |
DIN 267 strength classes are numerically identical to ISO 898-1/-2 (8.8, 10.9, class 8, 10). Effectively the predecessor system now replaced by the ISO 898 / ISO 3506 series.
