RockwellRW9157 Replacement Screw, Flange and Allen Key for Sonicrafter Oscillating Multitool Tool

Fits perfect

This work better than the original

Allows to use cheaper blades.

Replacement of good quality

Did not fit tool it was orderd for, but... Was able to use the washer on a bolt that fixed the issue.

N/A

I strongly recommend replacing the OEM screw and collar that comes with the Rockwell Sonicrafter with this part. Out of the box, the Sonicrafter has a fluted head screw with a hex driver which recessed into a collar/washer to attach the blades. After a couple months of use, I stripped the hex key hole in the screw. There is no edge to grab on to with pliers or any other tool. I tried a screw extractor with no success. I had to (very carefully) use an angle grider to cut the collar off so I could use vise grips to get the screw out. I ordered 3 of these replacements although they are a little different than shown in the picture. The advantage of these replacements is, in addition to using an allen wrench to loosen/tighten it, the screw has a 12mm hex head that should the allen wrench strip the hole, you can easily remove it with a 12mm wrench or socket. It also seems more durable than the OEM. I also keep a couple extras in the bag should I lose it or drop it somewhere it can't be retrieved.

Can't belive it fit our saw
