Will crack if you go strong
Worked perfectly for my couch legs. But did split on due to over tightening.

Weak and fragile. Don't waste your money. Try something else.
These particular thread reducers are horrible quality. I attempted to use one and it fractured under very little torque. I tried another and it broke as well. These are made of the most brittle and weak metal I have ever seen. I definitely cannot recommend this product.

Worked
Met my need - cat tree house that had 10mm sockets and replacement scratching post with 8mm hardware. Didn’t really need 5 but easier than going out to Home Depot and hoping they had one.

Easy to use
We ran into a problem with the old bed frame being 3/8” not 10mm and couldn’t find any adapters that were 8mm to 3/8”. So we used these 8mm to 10mm after using a tap to retread it to 10mm. Worked great.
