13C180

13C180 — is a specific tolerance code within the DTFR system that defines the allowable deviations of dimensional parameters and part strength. The value “13” indicates the accuracy category, “C” — the material type or manufacturing technology, and “180” — the maximum load or torque in N·m for which the part is certified. When selecting parts, you should choose 13C180 if the vehicle manufacturer or technical documentation requires this exact tolerance level, as other codes may not meet the required strength. Using this code guarantees compatibility with OEM specifications and safe operation under loads up to 180 N·m.
