For preschool: put ABC's or have them match the labeled nuts (shapes, numbers, letters) to the bolt. Nuts and Bolts Spelling Practice: build fine motor skills and practice spelling/phonics skills! This would make a fun center activity.
An idea for Tom to build for me for any students with fine motor difficulties and a fun activity for our grandkids. Homemade busy board for fine motor skill development - this is heaven for a curious kid!
