I took these screw-in nuts out of an outdated piece of furnishings, however you should purchase them at any ironmongery store. The press in ones work properly too, however they require a big spade bit too make it flush. I additionally needed to break a C-clamp for this threaded rod set-up, which is gloomy, however you’ll be able to’t make an omelette….. You additionally make this set-up by getting a threaded rod, flat knob, and metal dowel (requires drilling a gap within the threaded rod, which is hard). Now I drilled a half of inch gap within the entrance 2×2 and screwed within the screw-in nut utilizing a big hex key. Next put the threaded rod set-up into the nut, screw on the entrance 2×2 with two deck screws, and also you’re accomplished!! I marked off the desk with rulings in pencil, which appears fairly non permanent, however I will combat that battle later.
