Depending on age... you might just wanna replace the entire innards of the bolt with new stuff. I always like using new stuff on used guns, especially springs. Less worries down the road as far as, "how worn was it when I got it?" queries. Generally speaking, of course.
Most people neglect their tools. Especially simple firearms.
New guts for your Stevens 110E are available here:
