fastenerbased

Fastenerbased is a design philosophy and engineering approach that emphasizes the use of mechanical fasteners as the primary means of joining components in products and structures. It favors modular assemblies, ease of disassembly, repair, and upgrading over permanently joined methods such as welding or adhesive bonding. The term is used to describe practices across manufacturing, consumer electronics enclosures, automotive, aerospace, furniture, and industrial equipment where standard hardware such as screws, bolts, rivets, nuts, washers, and clamps forms the backbone of the assembly.

Core ideas include standardization of fasteners, deliberate incorporation of accessible fastening points, and designs that permit disassembly without specialized tools. Designers often apply design for disassembly (DfD) principles, select compatible materials to reduce galvanic corrosion, and specify preload targets to maintain joint integrity under load and vibration.

Advantages include improved serviceability and repairability, easier upgrading, recycling and end-of-life recovery, simplified supply chains through common hardware, and potential cost savings in high-volume production. Disassembly-compatible products can be repaired rather than discarded.

Challenges include slower initial assembly in some cases, risk of loosening under vibration or thermal cycling, corrosion concerns, weight penalties, and potential leakage paths in sealed assemblies. Requires careful tolerancing, thread engagement, and sometimes anti-loosening features (lock washers, thread-locking compounds) and protective coatings.

Examples and applications include consumer electronics chassis and mounting rails, automotive panels and interior components, modular furniture, industrial machinery housings, aerospace fixtures, and robotics systems that prioritize field serviceability.

Standards and practices involve reliance on established standards for fasteners (ISO, DIN, ANSI/ASME), including torque specs, preload classes, and thread engagement guidelines. Designers consider material compatibility, corrosion protection, and forces acting on joints, and may adopt design guidelines for disassembly to facilitate repair and recycling.
