Key benefits - Secure, reversible connections: double-end M20 threading lets you join two threaded components firmly without permanent fasteners. - Long-lasting performance: made from 304 stainless steel for high strength, corrosion resistance, and resistance to deformation. - Easy to match and replace: standard M20 thread and a range of lengths (110–190 mm) cover common assembly and repair needs. Product features - Thread: Double-end M20 threads on both ends for connecting two threaded parts. - Material: 304 stainless steel — durable, rust-resistant, and suitable for indoor and sheltered outdoor use. - Color: Silver tone finish for a clean, neutral appearance. - Length options: Total length between 110 mm and 190 mm (select the size you need). - Package contents: 1 x double-end bolt. Compatibility and function - Designed to mate with standard M20 internally threaded parts, nuts, or inserts. - Ideal for applications that require joining two components along a straight axis while allowing later disassembly or adjustment. - Works where a single continuous fastener is needed through multiple elements or to extend a threaded connection. Practical use scenarios - Assembling or repairing scratching columns: securely connect posts, bases, and platforms that use different thread sizes or require a through-bolt connection. - Furniture and fixture repairs: replace or extend internal threaded studs in modular furniture, display stands, or mounting brackets. - DIY and light construction tasks: join poles, threaded tubing, or fixing plates when a clean, removable connection is required. Why choose this part - Material and construction reduce the need for frequent replacement due to corrosion or bending. - Standard M20 sizing simplifies sourcing matching nuts or inserts. - Single-piece double-end design reduces assembly complexity compared with separate studs and couplers.
