• Dual End Thread Linking Framework: Threaded outlines set on both sides of the connector create concealed tight joints between wooden components with no extra independent fasteners needed to complete stable wood assembly combinations
• Self-Penetrating Spiral Insert Layout: Molded sharp spiral segments sink evenly into solid wooden slabs without pre-drilled openings, simplifying full assembly workflows and reducing uneven surface splitting on timber surfaces
• Universal Wooden Frame Matching Unit: Standard double-ended linking piece works for all kinds of wood structure assembly such as bed support frames, stair skeletons, storage cabinet frames and exterior wooden construction frameworks
• Coated Monolithic Metal Solid Structure: Hard unified metal core wrapped in outer surface covering retains consistent intact outline through long term placement amid fluctuating surrounding environmental conditions
• Variable Size Spiral Spec Layout: Multiple spiral thickness and total length options match wooden panels with different depth measurements to deliver flexible linking solutions for diverse timber assembly building requirements
