Combi Washer Screw

Combi washer screws incorporate an integrated serrated flange washer directly beneath the head, eliminating the need for a separate washer. The serrations bite into the mating surface to provide exceptional resistance to loosening under vibration and dynamic loads.

These screws are ideal for sheet metal fabrication, automotive sub-assemblies, HVAC systems and structural connections where secure, vibration-resistant fastening with improved load distribution is required.
