As other reviews here testify, these are too easy to round off. But once you’ve got the old one with the rounded head out (easier said than done) the replacement does the job and is reasonably priced.
Bad design shimano, efficient service from sjscycles

Constoo easy to round of the socket hole
These appear to be made of cheese, as it appears to be very easy to round off the Allen key hole. Not sure why they have such a small hole, and if what going to be that small a Torx hole would have got a better grip.

ConsWish they were in the US
ProsValue and prompt service
I don’t know why Shimano parts seem so hard to find in the US, eBay from a Chinese seller looked like the only option and they were sold out. SJS was prompt, easy and were sold at the correct price. Highly recommend. I will be back.

Perfit fit for Shimano Dura Ace disc brake set. I put too much force on the old screw, and thereby not getting traction anymore (so quality of the product is medium). Very satisfied with the wide offer of components from SJS

Kind Regards. JP 03/05/22
Will it fit an Alivio MTB lever BL M425?
14 Jul 2021

Can be used with 9170? Hex or Torx screw?
01 Aug 2019
Hi, it is 2mm hex / allen key. Thanks 01/08/19
Can I use this with R7020 Levers ?
18 Apr 2019
Hi, we don't have stock of Shimano part Y0F398030 which is the listed screw for your levers. However part 45946 is the same thread and looks very similar. I have found forums on the net that suggest it can be used as a replacement. Thanks. 24/04/2019
Will it also fit with the Ultegra BR-R8070?
29 Mar 2019
Yes, these also work with - Shimano Dura-Ace Di2 ST-R9170
- Shimano Ultegra Di2 ST-R8070
- Shimano Ultegra ST-R8020

Thanks - 01/04/19
Is this the new wider thread screw? Can i use it on ultegra r8020?

Hi there,

Yes this is suitable for ST-R8020.
