Product Details
From standards to delivery services, comprehensively meeting your fastener procurement needs.
Standard System
We can provide a variety of internationally certified products tailored to your requirements:
Custom parts require drawings or 3D models. We support customization of specific parameters including diameter, length, pitch, head type, and thread length.
Material & Strength
Materials can be customized to meet customer requirements:
Strength grades vary by product: 4.8, 8.8, 10.9, 12.9, and more, to meet diverse operating conditions.
Surface Treatment
Coating thickness can be customized per customer requirements. Salt spray test duration and coating material can be discussed and agreed upon with the customer.
Common treatments include zinc plating, nickel plating, black oxide, Dacromet, and hot-dip galvanizing. Coating thickness options: 5-25 μm.
