Frequently asked questions

What is ISO 4762?

ISO 4762 is the international standard for hex socket head cap screws (metric). This page lists the dimensional data size by size.

Is ISO 4762 the same as DIN 912?

They cover the same product family (metric socket head cap screws) but are different standards; check the dimension table for the size and tolerance you need before substituting.
