Ryobi OEM 522983001 String Trimmer Knob Assembly RY24001 RY40001 P2200 P2006A P2008 P2008VNM P2300 P2700

threads fit correctly

The screw size fit my old ryobi powerhead perfectly. The older screws had stripped out after many years and would tighten enough to hold the attachments in place. This part worked perfectly. I would have given it a 5 star if it had shipped with the needed washers.

Works ad advertised.

Works great but Ryobi should use better materials to make them as they don’t last as long as you would expect being made of metal. It would be nice if they made them with a better steel to last awhile but then you wouldn’t need to buy them so often and they would make less money

My Ryobi clamp screw stripped out and I almost bought a whole unit. Then this popped up and I was able to get the stripped one out and this fit in perfect. Nice to have back together. May just get another to have around...

I purchased this for my Ryobi Expand-It Trimmer. The bolt where the attachments connect to the trimmer had stripped. I am so glad there’s a replacement for just the bolt. It fit perfectly and tightened right up.

Had high hope for this. Using it to replace the original lock nub that lasted a few years but stripped recently. This came quickly and fitted correctly. Put and locked edger on and all worked fine, but when I swapped blower on to clean up, I noticed that at one spot the threat will skip. Upon inspecting the bolt section, I could see a lot of wear on the threats. It looked as if the bolt was made with soft metal. Maybe the factory forgot to heat treat the threats, or used wrong material to make the bolt. Oh well, need to think something else to use.
