Your Trusted Partner for Customized Fasteners

Sourcing customized fasteners, specialty bolts and screws, or custom rivets requires more than just competitive pricing—it demands a partner who guarantees quality, precision, and supply chain reliability. At Shijiazhuang TJJ TRADE CO., LTD., we combine over 20 years of integrated manufacturing expertise with China’s most efficient industrial supply chain to deliver made-to-order fasteners that meet your exact specifications. Whether you are an import manager seeking a stable OEM partner, a brand owner launching a new product line, or a wholesaler demanding consistent batch-to-batch quality, TJJ provides the technical capacity and commercial flexibility you need to win in your market.

The Sourcing Challenge for Import Managers & Brand Owners

We understand the frustrations that come with global fastener sourcing:

• Inconsistent Quality: Variations in hardness, thread pitch, or coating thickness can shut down your assembly line or lead to expensive field failures.
• Unreliable Lead Times: Missed shipping windows disrupt your inventory management and create tension with your own customers.
• High Minimums: Traditional factories often demand huge MOQs that lock up your working capital for products you haven’t validated yet.
• Lack of Technical Support: Many suppliers cannot provide the engineering feedback needed to optimize a fastener design for manufacturability and cost reduction.

TJJ was founded to solve these exact problems. As a foundry and machining powerhouse, we bridge the gap between high-volume, low-cost production and the precise, reliable quality that the US and European markets require.

Why TJJ? The "Powerful Factory" Advantage

When you choose TJJ, you are not just buying fasteners; you are accessing a fully integrated industrial partner. Our 20+ year history as one of China’s pioneering casting and fabrication facilities means we control every step of the process.

1. Comprehensive Quality Assurance

We operate under a strict ISO 9001:2015 quality management system. Our in-house laboratory performs tensile testing, hardness (Rockwell/Brinell), salt spray testing, and dimensional verification using vision inspection systems. Every batch of specialty bolts and screws is traceable to its raw material heat number.

2. True OEM/ODM Design Partnership

Our engineering team has decades of combined experience in cold heading, hot forging, and CNC machining. We actively collaborate with your design team to recommend material substitutions (e.g., upgrading from 304 to 316 stainless for corrosion resistance) or thread modifications that reduce overall costs without sacrificing performance. This is especially critical for custom rivets and complex customized fasteners used in safety-critical applications.

3. High-Speed Delivery & Flexible Terms

Located in the Shijiazhuang industrial corridor, we benefit from rapid raw material availability and excellent logistics connectivity to Tianjin Port and Beijing Airport. Our typical lead time for specialty bolts and screws is 20-30 days from drawing approval, and we routinely ship partial orders to help you manage inventory. We work on FOB, CIF, and DDP terms to major US gateways (Los Angeles, Long Beach, Chicago).

Our Product Range: Technical Depth

We specialize in complex geometries and non-standard configurations that typical fastener stocklists cannot supply.

* All specifications are for reference only. Final parameters subject to engineering drawing approval and order confirmation.

Coating & Finish Options

We offer a wide range of surface treatments to meet US environmental and performance standards: Zinc Plating (RoHS), Hot Dip Galvanizing (ASTM A153), Dacromet, Geomet, Phosphate & Oil, Black Oxide, and specialized PVD coatings for high-temperature or corrosive environments.

Real Applications, Real Solutions

Our fasteners are trusted across demanding industries:

• Automotive & Heavy Truck: Custom rivets for brake assemblies, specialty bolts for chassis mounts. Grade 10.9 and 12.9 structural components.
• Construction & Infrastructure: High-strength structural bolts for steel frame buildings, anchor bolts, and base plates.
• Industrial Machinery: Precision shoulder screws and custom threaded fasteners for conveyor systems and hydraulic equipment.
• Renewable Energy: Corrosion-resistant stainless steel bolts for solar panel racking and wind turbine assembly.

We understand that a fastener failure is not just a product failure—it’s a safety liability. That is why we treat every customized fastener order with the highest level of engineering rigor.
