ISO 4017 — Hexagon head screws, full thread
ISO 4017 is the international standard for fully threaded hexagon head screws, and the current replacement reference for DIN 933 in most new specifications. Naming the standard and the property class together is what makes a fastener purchase unambiguous.
What it covers
- Head and thread dimensions across the size range
- Property classes (8.8, 10.9, A2-70 and related) and what they imply
- Marking requirements on the head
Documents you can ask for
- Material certificate naming the property class
- Coating and corrosion performance where specified
- Dimensional report on request
