Du-Bro DUB379 Fully Threaded Rod 4-40 x 12"

The Du-Bro® DUB379 is a fully threaded 4-40 x 12-inch steel rod — a heavy-duty linkage component for RC aircraft, cars, and boats. The full-length 4-40 thread gives you maximum flexibility in positioning your clevis, ball link, or rod end anywhere along the rod’s length, making it easy to dial in exact control throws and linkage geometry without being locked into a fixed thread zone. The 4-40 thread is a stronger standard than 2-56, making it the preferred choice for higher-load control linkages on larger platforms where extra rigidity and strength are needed. At 12 inches, it’s sized for shorter linkage runs and can be trimmed to the exact length needed for your application. Compatible with the full range of Du-Bro and aftermarket 4-40 clevis, ball links, and rod ends.
