Product Information
Housing
While the advantages of hot-dip galvanizing were seen as also having potential for bolts used in houses, the hot-dip galvanizing process produced joining defects. To address this problem, ISK developed original screw precision standards which were successfully incorporated into its products.

The results of this undertaking are now applied in foundation anchor bolts, structural coupling bolts, bolts for bearing walls and bolts for exterior wall panel mounting used by major prefab housing manufacturers.
