Should you always design parts with room for assembly tools?

• A. Yes
• B. No
• C. Only for large assemblies
• D. Only if time allows

Answer: (A)

Planning for the actual tools used in assembly is essential. When you design parts, you should leave clearances and access for the tools that will engage fasteners, align features, or press or snap parts together. This prevents tool collisions with nearby geometry, avoids misalignment or damaged threads, and speeds up assembly by reducing the need for rework or disassembly. It also supports easier maintenance and possible automation, since a robot or technician can reach sockets, hex keys, screwdrivers, or torque wrenches without fighting tight corners or hidden fasteners. While there are occasional design choices that hide fasteners or use special fixtures, the default best practice is to incorporate room for tools from the start so assembly is reliable and efficient.
