Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical application of this cam lock? **A**: It is used in wooden furniture manufacturing, particularly for flat-pack or modular furniture, to join panels securely without tools. It is suitable for applications requiring repeated assembly and disassembly. ### Q: What are the key dimensions and tolerances? **A**: The cam diameter ranges from 15 to 25 mm, thread size is M6 to M8 (ISO 261), and engagement depth is 8 to 12 mm. Critical dimensions are held to ±0.1 mm per ISO 2768-m. Always verify these values with the supplier for your specific model. ### Q: What materials and finishes are available? **A**: The cam is made of zinc alloy, the screw is steel, and engineering plastic may be used for certain parts. Surface finishes include zinc or nickel plating per ISO 4042. Material grades follow ASTM B86 for zinc alloy. Confirm exact materials with the manufacturer. ### Q: How many assembly cycles can it withstand? **A**: The cycle life is specified as 10,000 to 20,000 assembly/disassembly cycles. This is a reference range; actual durability depends on usage conditions and should be verified with the supplier. ## 6.
