Which is used to fix backs onto cupboards and bottoms onto boxes?

• A. Panel pins and veneer pins
• B. Knock down fittings
• C. Steam bending
• D. Jig

Answer: (A)

Using small pins such as panel pins and veneer pins is the right approach here. These are short, thin nails designed for fixing thin back panels to cupboards and base panels to boxes. They grip well without splitting the edges and can be driven flush or slightly below the surface, leaving a neat finish that’s easy to fill if desired.

Knock down fittings are for temporary or dismantlable assemblies, not for permanently fixing backs or bottoms. Steam bending is a process to shape wood, not a fastening method. A jig is a tool to guide cuts or drilling, not how parts are joined.
