Double Ended Screw
The double ended screw is a highly versatile and structurally critical fastener designed to provide strong, seamless joints across dual interfaces, commonly bridging wood-to-wood or wood-to-metal applications. Over our 14 years of manufacturing, we have mastered the precise thread-rolling technology required to produce the double ended screw with perfect concentricity, ensuring that both threaded ends align flawlessly with zero axial deviation.

Over our 14 years of manufacturing, we have mastered the precise thread-rolling technology required to produce the double ended screw with perfect concentricity, ensuring that both threaded ends align flawlessly with zero axial deviation. We understand that in furniture manufacturing, solar mounting systems, and machinery assembly, a double ended screw must withstand immense shear and pull-out forces. This is why we use strictly certified, high-tensile carbon steel and stainless steel wires sourced from reputable domestic steel mills. Our deep integration into our clients' product development stages has allowed us to supply highly specialized fastening solutions to numerous public enterprises, earning a stellar reputation for delivering structural integrity where standard screws fail.
For global importers, sourcing your double ended screw directly from our source factory provides a major advantage in supply chain stability and purchasing efficiency. By splitting our production into a cost-optimized manufacturing facility in Shangrao, Jiangxi, and a dedicated sales and service hub in Hangzhou, we deliver premium products with highly competitive pricing and direct technical support. We implement strict quality checks throughout our daily production run, which exceeds 1 million pieces across our factory lines. We stand behind our manufacturing quality with a comprehensive 1-year product warranty and a transparent damage-compensation policy - if any goods arrive damaged due to our logistics or manufacturing fault, we will reissue the products or issue a refund immediately. If your engineering team is designing a custom mounting project, we can analyze your technical drawings and provide prototype samples in just 15 days, with free existing samples available to help speed up your validation process.

Packaging & Shipping
We customize our packaging based on product volume and customer requirements. Small-volume orders are packed in sturdy, moisture-resistant cardboard boxes, while high-volume bulk cargo is securely stacked on heavy-duty wooden pallets and wrapped in protective film to withstand long-term marine transit and prevent cargo shifting.
After-Sales Service
We have a dedicated, professional after-sales support team to ensure your complete satisfaction. If you encounter any technical issues or quality concerns post-delivery, we promise to respond within 24 hours. If any transport damage or product defects are found to be our responsibility, we will quickly handle replacements or refunds.
Payment Terms
For standard products, we require a 30% advance deposit, with the remaining 70% paid after successful quality inspection and quantity verification before shipment. For customized double-ended screws requiring custom mold development, the payment process is 50% pre-payment, with the 50% balance paid upon final inspection and release.
