Steel Knurled Insert

This steel knurled insert is an accessory widely used for fastening in mechanical assemblies, furniture construction, and general hardware applications. Primarily crafted from carbon steel, it offers high hardness and exceptional load-bearing capacity. The surface features a knurled finish, significantly increasing friction; once embedded, it locks securely in place, resisting stripping or loosening far more effectively than standard inserts. Customization options are also available for materials such as stainless steel or brass.

Manufactured via precision turning, these inserts feature precise dimensions, ensuring a tight and seamless fit with mating components. The surface can undergo various protective treatments-such as zinc plating, chrome plating, electrostatic painting, black epoxy coating, or anodizing-to enhance corrosion resistance. This makes them suitable for a wide range of applications, including industrial machinery, furniture hardware, and equipment enclosures. Both the knurling pattern and dimensions can be adjusted according to technical drawings, and OEM/private labeling services are readily available.

We also offer a sample service, allowing you to test locking performance and friction firsthand to ensure complete confidence before placing an order. Our packaging-consisting of cardboard cartons on wooden pallets-ensures that the knurled surfaces remain undamaged during transit, preserving their full frictional integrity. Shipments are dispatched via sea freight from the ports of Ningbo or Shanghai, utilizing established logistics channels to ensure reliable and secure delivery. Payment is processed via Telegraphic Transfer (T/T), providing a simple and streamlined transaction process. Lead times are strictly controlled, and quality is continuously monitored throughout production. Whether for mechanical assemblies or furniture hardware, this steel knurled insert represents a practical, reliable, and robust choice.
