Adjustable lifting screws (also known as adjustment screws, leveling bolts, telescopic screws, timber house connectors) are specialty hardware for height adjustment and horizontal leveling of timber house posts, consisting of a fully threaded rod, adjustment nut, and square base plate. Our lifting screws include models TG-2025, TG-2220, TG-3020B, TGU-3020A, and TG-1420, with rod diameters from M14 to M30 and lengths of 200-250mm, made of high-strength galvanized steel with anti-rust paint or electro-galvanized finish. By rotating the adjustment nut, post height can be precisely adjusted for horizontal leveling and fine height tuning. Widely used for post base leveling in timber houses, light wood framing, and prefabricated buildings, as well as height adjustment for heavy timber house posts, with customizable U-shaped opening sizes per customer requirements.
