Why choose thermal black oxide

Thermal black oxide provides a durable, non-reflective surface that reduces glare and offers modest corrosion resistance compared to bright finishes. It also enhances wear resistance and gives a sleek, professional appearance for fastened assemblies.

Applications

Ideal for automotive, machinery, fabrication, and industrial equipment where high-strength fasteners are required. Use in assemblies that demand a secure clamp with a clean, low-profile look.

Care and installation tips

To ensure proper seating and torque, use a compatible hex drive tool and follow standard installation practices for alloy steel fasteners. Apply a suitable thread lubricant if required by your application and fastener environment.
