Introduction
We provide custom manufacturing services for washers, bolts, pins, shafts and chain components based on customer drawings or samples.
These components are widely used in mechanical assemblies, fastening systems and industrial equipment where reliability and dimensional accuracy are critical.
Washers are commonly used to distribute load and improve fastening stability, helping prevent loosening and wear in bolted connections.
We provide custom manufacturing services for washers, bolts, pins and chain components for various industrial applications. For example, we have produced different types of fasteners such as double threaded fasteners and coated bolts for specific requirements.
Product Range
We manufacture a wide range of fastening and mechanical components, including:
- Flat washers and special washers
- Bolts and custom fasteners
- Pins and shafts
- Chain components and connectors
- Assembly-related metal parts
These parts can be produced individually or as part of a complete assembly solution.
For corrosion-resistant applications, we also supply surface-treated fasteners such as dacromet coated bolts and pins used in automotive and outdoor environments.
Manufacturing Processes
Depending on product requirements, we support multiple manufacturing methods:
- CNC machining for precision components
- Forging for high-strength parts
- Casting for complex shapes
- Surface treatment (galvanizing, plating, coating)
We select the most suitable process based on material, tolerance and application.
For applications requiring sealing and chemical resistance, related components such as PTFE gaskets are often used together with fasteners.
Applications
These components are widely used in:
- Industrial machinery and equipment
- Automotive fastening systems
- Construction and structural assemblies
- Agricultural and heavy equipment
- Chain and transmission systems
They are especially suitable for applications requiring durable fastening and reliable mechanical connections.
For structural applications, hardened washers such as ASTM F436 washers are commonly used together with high-strength bolts to ensure load distribution and joint stability.
You can view one of our washer projects here.
F436 washers are widely used with high-strength bolts to distribute load and prevent joint failure in structural applications.
Quality Control
We ensure each component meets dimensional and performance requirements through inspection of size, surface condition and material properties.
Inspection standards can be customized based on project requirements.
Custom Manufacturing Capability
We support custom production based on:
- Drawings (PDF, STEP, CAD)
- Samples
- Functional requirements
Customization options include:
- Size and tolerance
- Material (carbon steel, stainless steel, brass, etc.)
- Surface finish
- Heat treatment
- Assembly requirements
For example, in some applications, these components are combined with bearing assemblies to form complete mechanical systems. You can also explore our needle bearing and shaft assembly solution here.
