2.5mm Threaded Rod and Couplers
Metric pushrod hardware in the 2.5mm size lets builders use fine-thread clevises and links on smaller models, and this category covers the all-thread stock and couplers that go with it. These parts join a stiff carbon pushrod to a threaded end that accepts standard hardware.
All-Thread and Carbon Couplers
The 2.5mm all-thread provides the threaded rod itself for making up a pushrod. Carbon tube couplers then adapt a carbon rod to threaded ends: versions are offered to join 3mm and 4mm carbon tube to 2.5mm threads, and a two-pack couples 4mm carbon tube to 3mm threads.
Combining a lightweight carbon center section with short threaded ends keeps a long pushrod rigid without adding much weight, a common approach on larger control surfaces. Thread size matters when pairing with clevises, so confirm the coupler ends match the hardware you already run.
Check the sizes on this page to match the couplers to your carbon rod and clevises.
