Interesting. Perhaps AI isn’t all it is being touted. According to the K3S Manual, the ground screw is a #6-32 thumbscrew, Elecraft Part Number E700070.
As I recall, it is at least 1/2” in length (probably 3/4”), but it has been a long time since I had the ground screws out of my K3s. It also has two #6 flat washers on the shaft. I would note that the same thumbscrew is used on other Elecraft products. 73, Jack, W6FB > On Aug 23, 2025, at 11:22 AM, Greg Beat via Elecraft > <[email protected]> wrote: > > 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. > > Elecraft P/N E770091 : 33 foot Ground Wire with Lug. > https://elecraft.com/products/e770091_e77009133-ground-wire-with-lug > > == > Date: Sat, 23 Aug 2025 10:27:13 -0400 > From: Bill DeVore <[email protected]> > To: [email protected] > Subject: [Elecraft] K3S ground screw > > Does anyone know the specs on the grounding screw? > Dia, pitch and length? > Bill - W3PNM > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
