DIN 933 — Hexagon head screws with full thread
DIN 933 is the German standard for fully threaded hexagon head screws. It has effectively been superseded by ISO 4017, and the two are dimensionally close — but they are not identical in every size, so a specification should name the one it wants.
What it covers
- Dimensions across flats, head height and thread length
- Tolerance classes for the product
- Relationship to ISO 4017 and where the two differ
Documents you can ask for
- Material certificate and property class (for example 8.8)
- Dimensional report on request
- Coating specification and salt-spray result where applicable
