20 Pcs Thread Reducing Nuts, M8 Male to M6 Female Thread Screw Sleeve Bolt Conversion Nuts, Threaded Reducers Thread Adapters, Thread Repair Screw Reducer Adapter Insert Kit

Exactly as described. Just what I needed to adapt a branding iron part. Fast shipping.

Worked great. Needed to reduce an 8mm threaded hole to receive a 6mm threaded rod. I used thread locker to hold the insert and keep it from backing out. Glad I found these.

Worked perfectly and are of good quality.

Size and fit are exactly as described, but didn't work for my application. I was using these to remove an M6 bolt that had a missing screw head. Applying even very slight torque, they snapped in two. Ended up drilling out the screw.

These are perfect for the conversion of a m6 to an m8. These are not easy to find in the hardware store, but for the price of what it would be for one or two at a hardware store you can have some extras in your assortment of screws/adapters and such.

Was using them for a female end for a dowel rod I am using but the flat head end for screwing it in is so cheaply made that half of them cracked in some way. I was able to force work then in after they cracked. But I almost had to order more to finish my job.

I use them in Lamp building. Good quality.

Advertised as iron with stainless steel finish, but they don't even stick to magnetic surfaces. They're very light and feel more like aluminum. So far they seem like good quality but I doubt they will hold up to what I intended them for. Would rate higher if advertised correctly.
