Review on Uxcell Furniture M6X15Mm Threaded Interface by John Love

I tested these inserts on softwood scraps and also on a walnut table. With soft woods I can use an 8mm drill bit and screw in the insert with little effort. If I drill a 10mm hole instead, the insert loses strength. A 10mm hole works very well on a walnut. I've looked through literally hundreds of offers on Revain. Hardwood metric inserts are not easy to find in the US. I'm glad I have them!
