Furniture Connector 15mm Cam Fittings Pre-inserted Nuts Dowels (M6*40MM) 15Sets

These connectors were exactly what I needed to replace two on a TV stand which got damaged during a move (bent at 45 degrees and, of course, when you try to straighten them they just snap). Hence it's five stars from me.The one thing to note is that the picture on Amazon shows a white nylon "nut" on the M6 thread. These nylon parts were not supplied, just the posts and the silver cams (as per my photo) - 15 of each.

They were exactly what I needed to secure the cupboard panels with minimum visible fixings.

Great. Did the job.
