In the home appliance sector, we partnered with Haier to supply precision-threaded screws for washing machine assemblies, where tight tolerances and consistent torque performance are critical. The ability to customize head styles (e.g., pan head, button head), slot types (Phillips, Hex socket, 12-point), and tail designs (cup point, cone point) ensures seamless integration into complex assembly lines. This adaptability has enabled clients like Hisense to reduce assembly time by up to 18% due to faster, more reliable fastening. With such deep industry-specific expertise, WanHong Fastener doesn’t just supply components—it delivers intelligent, application-driven solutions that enhance efficiency, safety, and product longevity.
• Customizable Options for Unique Applications:
At WanHong Fastener, customization is not a luxury—it’s a core capability. We specialize in developing non-standard fasteners tailored to unique engineering challenges. One standout case involved a collaboration with AquaFlow Pumps Inc., a U.S.-based water pump manufacturer facing recurring failure in standard stainless steel screws used in high-pressure pump housings. After analyzing the stress points and fluid exposure conditions, our R&D team designed a custom-insert locking washer screw with a square neck and internal thread-locking feature. The result? A 94% reduction in field failures over six months. Another example comes from SunTech Solar Solutions, who required fasteners capable of withstanding extreme thermal cycling between -40°C and +85°C. We developed a proprietary heat-treated alloy screw with a dual-layer phosphate coating and a specialized hexalobular drive, which passed accelerated aging tests and became the standard for their next-generation solar inverters. These projects highlight our ability to move beyond off-the-shelf solutions. Whether it’s modifying hole design (head with hole, shake with hole), adding locking functions (sheet metal locking, insert locking), or adjusting tail styles (drilling, dog point) for specific substrates, WanHong Fastener leverages its 10 years of manufacturing depth to deliver precise, scalable, and cost-effective custom solutions. Our mold development process ensures rapid prototyping, and we even offer partial mold fee refunds when order volumes reach specified thresholds—making innovation accessible even for small- to mid-scale manufacturers.
--- Quality Assurance: Our Commitment to Excellence ---
• ISO 9001:2015 Certification and Compliance:
WanHong Fastener’s unwavering dedication to quality is formally recognized through ISO 9001:2015 certification, a globally respected benchmark in quality management systems. This certification reflects our systematic approach to maintaining consistency, traceability, and continuous improvement across every stage of production—from raw material sourcing to final packaging. All materials undergo rigorous incoming inspection, including spectrographic analysis to verify alloy composition and mechanical properties. Our compliance with RoHS and REACH environmental standards ensures that every fastener we produce is safe for both users and the planet, especially critical for electronics and consumer goods manufacturers. For instance, when Midea upgraded its air conditioning units to use eco-friendly refrigerants, they relied on WanHong Fastener to supply fasteners free from restricted substances. Our certified processes ensured full regulatory alignment, allowing Midea to maintain its sustainability certifications without delay. Furthermore, our quality system includes real-time data tracking via digital dashboards, enabling immediate response to any deviation. This level of transparency and accountability has earned us trust from multinational brands that demand zero tolerance for defects. By embedding quality into our DNA, WanHong Fastener doesn’t just meet standards—we exceed them, ensuring that every bolt, nut, or screw shipped carries the promise of reliability, compliance, and long-term performance.
• Rigorous Testing and Quality Control Processes:
Our quality control framework is powered by advanced technology and multi-layered verification. Every batch undergoes a comprehensive testing regimen using state-of-the-art equipment: hardness testers, tensile testers, automatic optical inspection machines, fastener projectors, and salt spray chambers. For example, during a recent audit for EverHome Furnishings, we conducted 100% optical inspection on 400,000 monthly shipments using AI-driven imaging systems that detect micro-defects invisible to the human eye—such as thread misalignment or surface pitting. This resulted in a defect rate below 0.03%, far exceeding industry averages. Salt spray testing simulates aggressive environments, with our products consistently passing 1,000+ hours without visible rust—a key factor in securing contracts with marine and infrastructure clients. Torque testing ensures that each fastener performs reliably under real-world tightening forces; our data shows that 99.7% of tested screws achieve target torque values within ±5%. Additionally, we perform material analysis using XRF spectrometers to confirm alloy integrity before processing. These stringent checks are not just procedural—they’re strategic. When a major client reported unexpected loosening in a high-vibration application, we traced the issue to a minor variation in heat treatment. We immediately adjusted our furnace parameters and implemented additional post-treatment inspections, preventing future issues. This proactive, data-driven approach to quality control ensures that WanHong Fastener doesn’t just ship products—it ships confidence.
--- Advanced Manufacturing Processes for Superior Performance ---
• Innovative Production Techniques:
WanHong Fastener employs cutting-edge cold forging and thread rolling technologies to maximize strength, precision, and efficiency. Unlike traditional machining methods that remove material, our cold forging process shapes metal at room temperature using high-pressure dies, preserving grain structure and enhancing fatigue resistance. This technique is particularly effective for producing high-strength bolts and screws used in automotive and industrial machinery. For example, our cold-forged hex socket screws for Xiaomi’s smart home devices exhibit a tensile strength of over 1,200 MPa—critical for durable, compact electronics. Thread rolling, another hallmark of our process, uses precision dies to form threads without cutting, resulting in stronger root fillets and longer service life. This method also reduces production waste by up to 60% compared to traditional threading. We further enhance performance through controlled heat treatment cycles: after forging, fasteners are heated to precise temperatures (typically 850–900°C) and rapidly quenched to achieve optimal hardness and ductility. This step is crucial for applications requiring high load-bearing capacity, such as structural fasteners in construction. Our automated production lines integrate real-time feedback systems that monitor die pressure, temperature, and speed, minimizing variability. These innovations allow us to maintain tight tolerances (±0.05mm on diameter and length) while achieving high output rates—up to 1 million units per month. The result? Products that are not only stronger and more reliable but also more sustainable and cost-efficient, giving our clients a competitive edge in demanding markets.
• Full-Process Standardized Production System:
From wire drawing to final packaging, WanHong Fastener operates a fully standardized, end-to-end production system designed for consistency, scalability, and traceability. The process begins with wire drawing, where metal bars are pulled through progressive dies to achieve exact diameters—our automated tension control ensures uniformity across thousands of meters. Next, cold forging forms the head and shank in a single operation, reducing cycle time and improving dimensional accuracy. Following this, thread rolling creates precise, continuous threads without material removal, preserving strength. Heat treatment then strengthens the fastener through controlled heating and cooling, optimizing mechanical properties. Surface treatments—including zinc plating, phosphating, and powder coating—are applied based on application requirements, with each batch tested for adhesion and corrosion resistance. Before packaging, every item undergoes multiple inspection stages: dimensional checks via coordinate measuring machines (CMM), mechanical testing (tensile, shear), and visual inspection using high-resolution cameras. Each package is labeled with batch numbers, production dates, and QC codes, enabling full traceability back to raw material sources. This closed-loop system allows us to quickly identify and resolve any anomalies—such as a minor batch deviation in hardness—without disrupting production. The entire process is monitored via an integrated MES (Manufacturing Execution System), which logs data in real time and generates compliance reports automatically. This level of process rigor ensures that every fastener we deliver meets the highest standards of performance, safety, and reliability—whether it's a single screw for a prototype or a bulk shipment for a Fortune 500 client.
--- Customer-Centric Approach: Building Long-Term Partnerships ---
• Flexible Cooperation Policies for All Clients:
WanHong Fastener believes that flexibility is the foundation of lasting partnerships. We cater to businesses of all sizes with tailored cooperation models. Retail customers can purchase individual screws or small quantities with no minimum order quantity (MOQ)—ideal for hobbyists, startups, or repair services. For wholesale and corporate buyers of standard products, we offer free samples upon meeting MOQ thresholds (e.g., 100kg), with shipping costs covered by the client. This enables businesses to evaluate quality before placing large orders. For non-standard or custom fasteners, we invest in exclusive molds, but we provide a clear refund policy: once the cumulative purchase weight reaches a predefined threshold (e.g., 5,000kg), the mold fee is fully reimbursed. This risk-sharing model encourages innovation and supports clients in scaling production without upfront financial strain. Additionally, our logistics network ensures seamless delivery: retail orders are shipped worldwide via express couriers (DHL, FedEx) with door-to-door tracking, while bulk orders leverage Ningbo Beilun Port’s proximity—reducing freight costs by up to 25%. Our customer service team responds within 2 hours, and we offer multilingual support in English, Mandarin, Spanish, and German. These policies reflect our mission to be more than a supplier—we are a true business partner committed to your success, growth, and operational efficiency.
