Got an old Sheldon 11X40 and need to replace the gib screws and lock nuts. The
1/4X28 screws are no real big problem but I have never seen any of the small
cross-section nuts like the factory used. No room for standard nuts. Any ideas?

1) take smaller nuts (say, 10-32) and drill and tap up to 1/4-28.

2) If it is thickness you are worried about, face down standard
nuts by using a threaded mandrel to hold them.

3) Fabricate your own! That's what lathes are all about.
