Overview
ISO 10663 has a regular hexagonal shape with a threaded connection in the center; the nut has special notches on the outside that cut into the metal when tightened.
Strength class ISO 10663
The strength class of an ISO 10663 nut is the maximum applied force at which the nut begins to fracture. DIN 6923 nuts are manufactured in strength classes from 6 to 12. From strength class 8 onwards, the nut is considered high-strength.
Materials for the manufacture of ISO 10663 spur nuts
ISO 10663 is manufactured in the following materials:
- Steel, which can be additionally coated with hot-dip galvanized, ordinary galvanized, yellow galvanized and zinc plated
- Stainless steel (A2, A4) does not need to be coated
Areas of application of the ISO 10663 nut
ISO 10663 is used in industrial construction, machine tool and instrumentation, etc.
In addition, the scope of application directly depends on the material of manufacture and the coating of the product:
- Galvanized steel offers good corrosion protection if the fastener is to be used in aggressive environments.
- Stainless steel allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.
