Du-Bro DUB145 Threaded Rods 4-40 x 30"

Du-Bro® DUB145 Threaded Rods are 4-40 x 30-inch steel threaded rods — a heavier-duty linkage hardware staple 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 on bigger platforms. At 30 inches, these rods give you plenty of length to cut to size for any linkage application. Compatible with a wide range of Du-Bro and aftermarket 4-40 clevis, ball links, and rod ends.
