Double‑head transfer screw bolts (Doppelkopf-Transferschraubenbolzen) Key benefits Durable and corrosion-resistant: Made from stainless steel 304 for long service life and repeated use in indoor and outdoor environments. Reliable connection: Double-head design provides a secure mechanical link between two components, minimizing movement and improving assembly stability. Flexible ordering and fit: Available in quantities of 1/2/5 pieces and specified as Size = M1 * L1 – M2 * L2 to match the mating parts precisely. What this product does Transfer screws/bolts are used to join two parts where one threaded section transfers the connection through or between components. The double-head configuration allows fastening from both sides or joining components with different thread depths or thicknesses. Important attributes Size specification: Size = M1 * L1 – M2 * L2 (use this specification to confirm compatibility with your existing fittings or drilling pattern). Material: Stainless steel 304 — resistant to rust, durable under regular mechanical load, and suitable for repeated installation/removal. Quantity options: 1 / 2 / 5 pieces to suit single repairs or small production runs. Item name: Doppelkopf-Transferschraubenbolzen (double-head transfer screw bolts). Practical applications Furniture assembly and repair: Securely join cabinet panels, shelving units, or frames where a hidden or through-fastener is required. Metal or mixed-material enclosures: Fasten sheet metal panels to frames or secure brackets where durable, corrosion-resistant hardware is needed. Small machinery and fixtures: Assemble fixtures, jigs, or assemblies that require repeatable removal and reinstallation without thread damage. Installation and compatibility tips Verify the Size = M1 * L1 – M2 * L2 against your component measurements before ordering. Use appropriate torque to avoid deforming the stainless steel 304 threads; stainless steel requires slightly different torque values than softer metals. For best results, pair with matching nuts or threaded inserts sized to M1 and M2 as specified. This product provides a straightforward, reusable fastening solution where a double-headed transfer screw is required.
