High-Precision Fasteners Manufacturer | Custom Bolts, Nuts & Screws Supplier

Introduction: The Core of Every Connection

Fasteners may seem small, but they are the unsung heroes of modern engineering. From skyscrapers and automobiles to medical devices and drones, precision fasteners hold the world together. The performance of every mechanical system relies heavily on the reliability and precision of its fasteners.

As a professional manufacturer of precision hardware components, our company provides a complete range of bolts, screws, nuts, washers, rivets, and custom fastening solutions. Every piece we produce meets stringent quality and dimensional standards, ensuring not only strength and durability but also consistency and interchangeability.


Product Description: Types of Fasteners We Offer

Our fasteners are designed for both standard and custom applications, covering multiple industrial needs. The main categories include:

  • Bolts: Hex bolts, socket head bolts, carriage bolts, and anchor bolts.

  • Screws: Self-tapping, machine, wood, and set screws.

  • Nuts: Hex nuts, lock nuts, flange nuts, wing nuts, and cap nuts.

  • Washers: Flat, spring, and sealing washers to enhance load distribution.

  • Rivets & Pins: Permanent joints for mechanical assemblies.

  • Custom Fasteners: Tailored to customer drawings or samples.

Each fastener type is precisely machined to meet mechanical strength, dimensional accuracy, and surface requirements.


Material Selection: Strength Meets Durability

The choice of material determines a fastener’s performance under specific environments. We offer a wide range of materials tailored to industrial demands.

Material Characteristics Typical Applications
Carbon Steel High strength, cost-effective Machinery, construction
Stainless Steel (304 / 316 / 410) Corrosion resistant, clean surface Marine, food processing
Alloy Steel (40Cr, SCM435) High tensile strength, heat resistant Automotive, aerospace
Brass / Copper Good conductivity and anti-corrosion Electronics, instrumentation
Titanium Alloy Lightweight, superior strength Aerospace, medical
Aluminum Alloy Light, rust-free, non-magnetic Drones, robotics

Each batch of raw material undergoes chemical composition and hardness testing before entering production. This ensures mechanical integrity and compliance with international standards such as ISO, DIN, ANSI, and JIS.


Surface Treatments: Protection and Performance

Surface finishing not only enhances the appearance of fasteners but also improves their corrosion resistance, wear protection, and durability. We employ multiple processes depending on product use and environmental exposure.

Common surface treatments include:

  • Zinc plating (white / yellow): Economical rust protection.

  • Nickel plating: High hardness and decorative appearance.

  • Hot-dip galvanizing: Thick coating for outdoor applications.

  • Black oxide: Anti-glare and moderate rust protection.

  • Dacromet / Geomet coating: Environmentally friendly and superior corrosion resistance.

  • Anodizing: For aluminum fasteners, enhances hardness and color options.

  • Passivation: Applied to stainless steel for improved corrosion performance.

Testing: All surface-treated fasteners are tested via salt spray corrosion tests, adhesion tests, and thickness measurements to ensure consistent coating quality.


Manufacturing Process: Precision from Start to Finish

Every fastener we produce undergoes a meticulous process flow supported by automation and strict quality control.

  1. Raw Material Selection: 100% inspection for hardness, size, and chemical elements.

  2. Cold Heading & Hot Forging: Shapes fasteners under controlled temperature and pressure.

  3. Thread Rolling / Cutting: Achieved by precision CNC machines for consistent threads.

  4. Heat Treatment: Enhances mechanical strength and fatigue resistance.

  5. Surface Treatment: According to customer specifications.

  6. Final Inspection: Includes tensile, torque, and hardness testing.
