These thread reducers convert a M10 (M10X1.5) threaded hole to a M8 (M8X1.25) threaded hole. These are 10mm long which allows them to be fully inserted in shallow threaded holes to prevent bottoming out or protruding. To assist in installation and removal, each thread reducer has a slot on the top for use with a flathead screwdriver.

Basically junk, very brittle metal! The moment they got any resistance whilst screwing them in the slot in the top two threads where you put the screwdriver head in snapped clean off. They’re now jammed part of the way in with no way to remove them. This happened on two of the adaptor sleeves so it’s not a one off fluke.I wish I’d gone to a hardware store instead now.

Inside is 8mm 1.25Outside is between 7/16 -20 and 11 1.50. I tapped 11 1.50 and it works but has slop. Red thread lock and wait, good enough for me

I have a Makita trimmer the has a 10 sleeve in the head. I needed to reduce it down to 8mm so this head will adapt to my electric Makita trimmer that has an 8mm bolt. No GO. Too big on outside (10mm) and too small in the 8mm inside.Beware these may not work on a Makita string trimmer. They look fine, but do not do the job. Wasted purchase.

Be very careful with these. The slotted top will break off easily.
