I'd like to attach a 1 1/8" thick table made of beech to a metal frame.
The metal frame normally attaches to a particle board top through 3/8" holes. An outer piece of plastic is first inserted into the particle board through the hole in the frame, and a thin plastic pin exerts pressure to create a lock.
How can I attach a metal frame with pre-drilled 3/8" holes to a hardwood table top? I'd like not to drill matching 3/8" holes in the wood, and use hardware to do the coupling instead. Just using wood screws with a flange will require that I rely on tightening to keep the top from sliding sideways.
- Use a wood screw and a washer. To avoid sliding the screws must then be tightened hard, perhaps more than the wood can handle for long.
- Drill a 3/8" hole and use the same plug-and-pin technique. The large hole is needed to secure a frame to particle board, but it's an unsavoury solution for real wood because it introduces an unnecessary weakness.
- Use a wood screw, a washer, and some kind of jacket. The cylindrical jacket would be 3/8" on the outside, exactly the same depth (height) as the frame, and have a hole that matches the wood screw. What is such a jacket called at the hardware store?
- Thanks to WoodAirGrille's thoughts, "all I need" is to drill a hole through a wood plug, but that's beyond my ability.
