Du-Bro DUB891 Threaded Rods 4-40 x 48 in

The Du-Bro DUB891 Threaded Rods are 4-40 x 48-inch steel rods — the longest option in Du-Bro's 4-40 threaded rod lineup, designed for large-scale RC aircraft and platforms with long control linkage runs. The 4-40 thread provides greater strength than 2-56 for higher-load applications, and the 48-inch length handles even the longest fuselage pushrod runs without splicing. Compatible with standard 4-40 clevises, ball links, and rod ends.
