At Ananka, the following fastener geometries are produced to ISO 4032:
Every grade in the Ananka catalogue is available in this dimensional standard:
Threads are cut to ISO 261 metric coarse. Standard tolerance class is 6g (external) / 6H (internal) for metric, or Class 2A/3A for inch series. Fine-thread and interference-fit variants are available on request.
Every fastener produced to ISO 4032 undergoes 100% dimensional inspection with calibrated gauges. Traceability is maintained from mill certificate to shipment.
