10 Sub-Brands of Yuanpai Fastener – Your Complete Sourcing Guide

When you source fasteners from China, one size – or one brand – rarely fits all. Different applications demand different coatings, strengths, sizes, and packaging. That’s why Handan Yuanpai Fastener Manufacturing Co., Ltd. has built a multi-brand strategy: 10 specialized sub-brands, each focused on a specific fastener category, coating, or market need.

In this guide, we walk you through every sub-brand – from heavy-duty outdoor anti-corrosion to retail-friendly small packages – so you can quickly identify the right product for your next project.

Why Does Yuanpai Have 10 Sub-Brands?

Fasteners may look simple, but their performance varies enormously based on material, heat treatment, coating, and thread precision. A bridge in a coastal area needs hot-dip galvanized protection. A solar farm in the desert may require Dacromet coating. A hardware store needs small packaging for walk-in customers.

Instead of offering a “one-size-fits-all” catalog, Yuanpai created dedicated sub-brands. Each brand has its own production line, quality control, and inventory. This ensures:

• Consistent quality for each application

• Faster sourcing – you know exactly which brand to choose

• Better pricing – specialized volume production reduces waste

Below is the complete breakdown of all 10 sub-brands.

1. Wolf Warrior – Hot-Dip Galvanized Fasteners

Best for: Outdoor, high-corrosion environments (bridges, power towers, photovoltaic brackets, port machinery)

Coatings / Features: Thick hot-dip galvanized (HDG) coating – uniform, dense, excellent salt spray resistance, anti-aging

Main products: HDG bolts, nuts, flat washers, spring washers

Why choose Wolf Warrior: Outdoor fasteners face rain, salt, and UV. Standard zinc plating fails within months. Wolf Warrior’s HDG layer (typically 80–100µm) provides long-term anti-corrosion for 20+ years. If your project is exposed to the elements, this is your brand.

2. Changgu – High-Strength Fasteners (Grade 8.8 / 10.9 / 12.9)

Best for: Heavy loads, steel structures, heavy machinery, mining equipment, wind power, automotive chassis

Standards: GB 5783, GB 5782 (also available in DIN/ISO equivalents)

Features: Alloy steel (40Cr, 35CrMo, etc.), heat-treated, high tensile strength, fatigue-resistant

Main products: High-strength hex bolts, flange bolts, nuts

Why choose Changgu: When a project requires Grade 8.8, 10.9, or 12.9, standard fasteners won’t work. Changgu delivers the hardness, yield strength, and torque resistance needed for safety-critical connections. Every batch is tested for tensile and hardness.

3. Mingyang – Dacromet Coated Fasteners (Eco-Friendly Anti-Corrosion)

Best for: Automotive parts, precision machinery, rail transit, wind power equipment, and environments where hydrogen embrittlement is a risk

Coating: Dacromet (zinc-aluminum flake coating) – no hydrogen embrittlement, chrome-free, excellent salt spray resistance

Why choose Mingyang: Traditional electroplating can cause hydrogen embrittlement in high-strength steels. Dacromet coating eliminates that risk while providing superior corrosion protection (500–1000+ hours salt spray). It also withstands high temperatures. If your customer demands eco-friendly, high-performance coating – Mingyang is the answer.

4. Qinggang – New Standard Bolts (Universal Standard Fasteners)

Best for: General engineering assembly, equipment maintenance, wholesale hardware

Standards: Latest GB (Chinese national standards), also compatible with DIN

Features: Strict dimensional control, uniform specifications, wide compatibility

Main products: Standard bolts, nuts, washers

Why choose Qinggang: Not every project needs high-strength or special coatings. For everyday fastening – assembling machinery, repairing equipment, or supplying hardware stores – Qinggang offers reliable quality at a competitive price. Fully tested to meet national standards.

5. Changheng – Small Packaging Bolts

Best for: Hardware stores, home repair, furniture assembly, DIY, maintenance crews

Packaging: Individual small packages, clearly labeled, easy to store

Why choose Changheng: Retail buyers don’t want 25kg cartons. They need small quantities, clear identification, and convenient packaging. Changheng solves the problem of “loose bulk” sourcing. It’s designed for terminal retail – perfect for distributors supplying local hardware shops or online DIY sellers.

6. Jinlu 21 – Cost-Effective Standard Bolts (High Inventory)

Best for: Basic construction, high-volume daily maintenance, bulk purchasing with budget control

Features: Mass production, low cost, large stock, fast shipment

Why choose Jinlu 21: When price is the top priority and application requirements are basic (indoor, non-corrosive, general use), Jinlu 21 offers the lowest cost per piece among Yuanpai brands. Thanks to our 70,000-ton inventory, we can ship large quantities immediately. Ideal for contractors and hardware wholesalers.

7. Jin’an – High-End Blue-White Zinc Fasteners (Export Quality)

Best for: Foreign trade orders, electromechanical equipment, assembly lines that require both corrosion resistance and good appearance

Finish: Bright blue-white zinc plating, uniform color, precise tolerance, high corrosion resistance

Why choose Jin’an: Export markets demand consistent appearance and strict quality control. Jin’an fasteners undergo rigorous inspection including salt spray test, coating thickness, and dimensional check. The bright finish looks professional on finished products. If your buyer is in Europe, America, or Southeast Asia – Jin’an meets their expectation.

8. Wild Horse – Complete Series of Washers

Best for: All bolt applications – steel structures, machinery assembly, hardware wholesale

Products: Flat washers, spring washers, thickened washers, widened washers, non-standard sizes

Why choose Wild Horse: Washers are often treated as an afterthought, but poor-quality washers cause loosening and surface damage. Wild Horse specializes only in washers – with full size range, high flatness, and strong compression resistance. We supply washers that match every bolt from M3 to M64, standard or custom.

9. Steel Screw – Color Zinc Bolts (Decorative & Anti-Rust)

Best for: Home appliances, door/window assembly, furniture, light machinery, visible fastening points

Finish: Color zinc plating (yellow, blue, black, etc.) – bright, uniform, decorative

Why choose Steel Screw: Some applications require both rust protection and good looks. Steel Screw bolts combine a glossy color finish with reliable anti-corrosion performance. They make the final product look more refined. Widely used in furniture manufacturing, electrical enclosures, and interior structures.

10. Tianbao – Full Range Nuts (Including Lock Nuts)

Best for: Infrastructure, machinery manufacturing, hardware wholesale, equipment repair

Products: Hex nuts, lock nuts (nylon insert or all-metal), flange nuts, high-strength nuts, plain nuts, miniature nuts

Why choose Tianbao: Nuts must match bolts precisely – wrong threads or weak locking cause failures. Tianbao produces every nut type from standard hex to specialized lock nuts. Thread accuracy is 100% inspected. Whether you need Grade 8, Grade 10, or custom sizes, Tianbao delivers reliable locking force.
