The Serpent 411161 kit contains 1.5x10mm roll pins produced to consistent dimensions so parts stay aligned race after race. These steel pins are suited to securing shafts, linkages and small gear assemblies on common RC platforms.
Built to remain round and true under load, the pins reduce play and help maintain drivetrain integrity. Their length and diameter strike a balance between ease of installation and holding power in tapped or plain bores.
Before fitting, deburr and clean the hole to avoid misalignment. Drive the pin straight with light taps, and check for any wear on mating parts so the Serpent pins deliver reliable clamping without premature loosening.
