Yes, M42 screw mount lenses will work on K mount Pentax bodies, though you will need an M42 to K adaptor to do so.

Look in the "Lenses" link at the top of the page.

Screw mount lenses preceded current lens mounts (like the K mount, EOS, etc). To use them on Pentax DSLRs, you need an adapter and then to do stop down metering. Quite easy to do and (depending on the lens) quite worth it as well.

There are also different kinds of screw mount lenses though so make sure you get the M-42 kind.
Each screw type mount would need a different type adapter.

Be careful as well ... as T-mount and M42 mount are both 42mm in diameter ... just the thread pitch is different.

Best place to look of good quality M42 glass is actually here in the Marketplace within this forum ... as you will find the gear is well looked after ... unlike on eBay where it can be hit and miss with equipment quality.

Make sure that it is M-42 and will fit Pentax.
In your searches include "screw mount"..M-42..Pentax".
