The 1/4-20 x 3/4 Black Nylon Thumbscrews used in the new (2005 and later) 80mm Finder Brackets are almost unbreakable, but Lumicon still gets occasional requests for replacements. The LS2125 is a set of seven (7) 1/4-20 x 3/4 Black Nylon Thumbscrews. Also used as the quick-release knob for the LS1055 Laser Pointer Bracket.
