Both-Ended Screw
Products Description
Both-Ended Screws are specifically designed for scenarios requiring precise connection of two components, detachable adjustment, and stable connection in vibration environments. They are an engineering-grade solution integrating bidirectional threaded fastening, smooth rod guidance and positioning, and detachable reuse. Unlike self-drilling and self-tapping screws with their integrated drilling and tapping logic, or flange bolts with their heavy-duty integrated design, this product uses a core design concept of "coordinated threading at both ends + guided smooth rod in the middle." It addresses four key pain points faced by professional buyers: misalignment of two-component connections, difficulty in disassembly after long-term use, poor compatibility of components made of different materials, and easy loosening in vibration environments. Through optimized thread parameters and structural innovation, it provides precise connections, convenient maintenance, and long-term stability for equipment assembly, building connectors, furniture manufacturing, new energy equipment, and construction machinery, becoming a core component for scenarios requiring detachable connections.
Main Functions: Focusing on the core need for precise bidirectional fastening
| Precise Bidirectional Connection | The collaborative thread design at both ends, combined with a guide rod for positioning, ensures a coaxiality error of ≤0.05mm between the two components. This avoids abnormal noises and uneven structural stress caused by connection misalignment, making it suitable for high-precision equipment assembly, building connectors, and other scenarios. |
| Disassembled and Reusable | Cold-rolled threads and a lubricating coating design maintain thread precision even after more than 50 disassemblies, meeting the needs of equipment maintenance, component replacement, and scenario modification, reducing replacement costs and improving resource utilization. |
| Vibration-Resistant and Loosening-Proof Stability | Fine-pitch threads and an anti-loosening coating provide double anti-loosening protection, preventing loosening under high-frequency vibration and temperature cycling conditions. Connection stability is twice that of ordinary Double-Ended Threaded Bar, making it suitable for vibration environments such as machinery, rail transportation, and outdoor infrastructure. |
| Multi-Material Compatibility | Supports connection between components made of different materials, such as steel-aluminum, steel-plastic, and aluminum-composite materials, eliminating the need for additional adapters, simplifying the assembly process, and reducing selection and inventory costs. Spacing adjustment function: The central guide rod can be used as a spacing reference. By adjusting the position of the nut, the spacing between the two parts can be finely adjusted (adjustment accuracy ±0.1mm). This is suitable for scenarios that require precise spacing control (such as furniture splicing and equipment panel fixing). |
Design Advantages: Intelligent Optimization of Engineering Connections
Mechanically Symmetrical Guiding Design
Micro-guide marks at both ends of the thread ensure precise alignment during installation, preventing stress concentration and connection failure due to misalignment. This design makes installation more efficient, especially suitable for space-constrained engineering scenarios.
Stress-Free Installation Technology
Optimized thread design ensures more even stress release during installation. This technology ensures connection stability under repeated vibration conditions, avoiding the loosening problems common with traditional double-ended screws.
Versatile Design
Thread specifications conform to international standards, perfectly matching 95% of nuts and connectors on the market, eliminating the need for additional customization and significantly reducing engineering costs.
Why do professional engineering clients choose our double-ended studs?
In the engineering world, structural symmetry and balance are crucial to system performance. Our double-ended studs are not simply fasteners, but intelligent structural integration systems designed to solve deep-seated pain points in engineering connections. We understand that for professional buyers and engineering clients, long-term reliability, structural stability, and maintenance costs are far more important than initial price.
Double Threaded Bolt Compared to common double-ended studs on the market, our products fundamentally solve structural problems caused by connection asymmetry through innovative "force symmetry transfer" technology, precision manufacturing processes, and engineering-grade material selection. We offer not just products, but complete structural integration solutions from design to application.
