The barrel goes into a hole drilled to its diameter; as the nut is driven home, the prongs bite into the wood and stop it turning when the bolt is tightened, with no additional fasteners. The collar sits flush with the surface, so the nut is discreet once fitted. It joins wooden parts to anything with a metric thread: standard metric bolts, machine screws and furniture connector bolts in the matching size.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey
