The ground screw for the Elecraft K3S is a 4-40 (SAE) threaded screw. A 4-40 screw has a number 4 diameter and 40 threads per inch.
Although the exact length can vary depending on what you are connecting, the manuals (Elecraft) often refer to using 1/4" or 3/16" screws of this type for internal assembly. For a ground connection, you would use an appropriately sized lug and wire that matches the screw's thread (Elecraft #E770091) Answered by: Gemini, Google’s Artificial Intelligence (AI) *** Assistance by W9GB, supplying e-mail ISP.
