Du-Bro DUB144 Threaded Rods 4-40 x 12"

Du-Bro® DUB144 Threaded Rods are 4-40 x 12-inch steel threaded rods — a compact, heavier-duty linkage hardware option for RC aircraft, cars, and boats. The 4-40 thread is a larger, stronger standard than 2-56, making it the preferred choice for higher-load control linkages where extra strength and rigidity are needed — such as larger aircraft control surfaces, heavy-duty steering linkages, and throttle connections. At 12 inches, these rods are ideal for shorter linkage runs where the 30-inch DUB145 would leave too much excess material. Compatible with a wide range of Du-Bro and aftermarket 4-40 clevis, ball links, and rod ends.
