China is the world's largest producer of screws and fasteners, supplying construction, industrial, and manufacturing markets across the globe. With thousands of factories available, choosing the right screw manufacturer in China can significantly impact your product quality, costs, and long-term business success.

This guide outlines the key factors to consider when selecting a Chinese screw manufacturer—and explains why JLHY stands out as a trusted choice for global buyers.

1. Manufacturing Capability and Product Range

A reliable screw manufacturer should have in-house production capacity, not just trading capability. This ensures better quality control, stable lead times, and competitive pricing.

What to look for:

• Automated or semi-automated production lines

• Ability to produce various screw types and fasteners

• Consistent output for bulk and long-term orders

JLHY Advantage:
JLHY operates its own facilities in China, specializing in industrial fasteners such as coil nails, common nails, loose nails, and customized fastening solutions. Direct factory production allows JLHY to maintain strict quality standards and stable supply.

2. Quality Control and Certifications

Quality is one of the biggest concerns when sourcing screws from overseas. A professional manufacturer should follow recognized international standards and have a clear quality inspection process.

Key indicators:

• ISO or equivalent quality management systems

• Raw material inspection

• In-process and final product testing

• Clear documentation and traceability

JLHY Advantage:
JLHY implements a strict quality control system from raw material selection to final packaging, ensuring consistent strength, durability, and corrosion resistance across every batch.

3. Material Options and Technical Expertise

Different applications require different materials, such as carbon steel, stainless steel, or coated fasteners. An experienced manufacturer should be able to recommend the right materials based on usage and environment.

Important capabilities:

• Multiple material options

• Surface treatments (galvanized, polished, coated, etc.)

• Technical support for product selection

JLHY Advantage:
JLHY offers a wide range of materials and finishes, including stainless steel fasteners for corrosion-resistant applications. The technical team supports buyers in selecting the most cost-effective and reliable solutions.

4. OEM & Customization Capability

Many importers and distributors need OEM or private-label products. A strong screw manufacturer should be able to customize sizes, packaging, and branding.

Customization areas to check:

• Screw dimensions and specifications

• Packaging design and custom kitting

• OEM branding support

JLHY Advantage:
JLHY provides flexible OEM services, helping wholesalers and distributors build their own brands as well as the custom kitting service for small box packaging for screws.

5. Export Experience and Global Service

An experienced exporter understands international shipping, documentation, and market requirements, reducing risks and delays.

Look for:

• Experience with global markets

• Professional export documentation

• Responsive communication and after-sales support

JLHY Advantage:
JLHY has extensive experience serving customers in North America, Europe, and other international markets, offering reliable logistics support and clear communication throughout the order process.

6. Price Transparency and Long-Term Cooperation

The lowest price is not always the best choice. A trustworthy manufacturer offers transparent pricing, stable quality, and long-term partnership potential.

JLHY Advantage:
As a direct manufacturer, JLHY provides competitive factory pricing without sacrificing quality, making them an ideal long-term partner for importers and distributors.
