Fasteners. Hexalobular socket countersunk head screws, high head Ingestion-build-111333 Information related to propulsion energy1 Scope This International Standard specifies hexalobular socket countersunk head bolts and screws with high head (full loadability), of product grade A, and thread diameters from M3 up to and including M10 and property classes 4. 8, 8. 8 and 10. 9. NOTE 1 In comparison with ISO common countersunk head, the height of the head has been slightly increased in order to have screws with full loadability, in conformity with the mechanical properties
