Fine and Strong Thread Processed with an automatic thread rolling machine to produce a fine, strong thread that remains stable during tightening. PVD Vacuum Coating The surface is colored using PVD vacuum coating, giving a beautiful, textured appearance. An oxide film forms on the surface, providing longlasting color that resists fading. Enhanced Accessory Protection Gaskets are used during tightening to expand the touch area between accessories. This reduces stress concentration and protects the accessories, helping to minimize scratches and wear. Stainless Steel Material Made of stainless steel for durability and longevity. Applications and use scenarios Industrial and mechanical assemblies: ideal for tightening fittings and fasteners where thread stability and longterm durability are important. Decorative or exposed hardware: suitable for components that require a durable color finish and resistance to wear during assembly. Gasketinvolved assemblies: appropriate for applications that use gaskets during tightening to protect contact surfaces and reduce surface damage.
