Pentax-m smc 35mm f2 Focal screw issue

Hello everyone,

Just yesterday I got my first 35mm lens. Its a pentax-m smc 35mm f2 This one the focus wasnt working (all my lens were in some shape or form not working) but the optics look amazing. I pulled it apart and started cleaning the lot. looks like it was dropped in sand and was through the focusing screw. Everything is clean and looks like it will work however there is one part that has got me (m35 f2 part.jpg).

Does the focus screw on this part move? its firmly locked in place. When the guide rails are in, the whole focus system is locked in place. my logic says it should spin as both screws will spin in oppisite directions so to keep the lens front aligned while focusing. However I want some confirmation before I bust out the big guns to get it moving. currently i am soaking the part in isopropal achohol.

There is another forum post here I need help with the repair off a SMC-M 35mm f2.0 - but its difficult to see. I thank anyone who can clarify it for me and let me know if you need more photos.

Kind Regards
