Sheet Metal General Tolerances
For most sheet metal parts, standard general tolerances follow DIN ISO 2768-m (medium) unless otherwise specified in the drawing. Actual achievable tolerances depend on part geometry, material type, and chosen fabrication process.
| Item | Tolerance | Note |
| Linear dimensions | ±0.2 mm ~ ±0.5 mm | Depends on material thickness and process |
| Hole diameter | ±0.1 mm ~ ±0.2 mm | Smaller holes may achieve tighter tolerance |
| Bend angle | ±1° ~ ±2° | Varies with material and bend length |
| Hole & feature location | ±0.2 mm ~ ±0.5 mm | Relies on machine precision |
| Standard | DIN ISO 2768-m (medium) | Unless otherwise specified in the drawing |
Part lengths of up to 118" are available on our platform process dependent. Please inquire about anything larger. Tolerances listed here are minimums for an ideal case. Looser tolerances may be required depending on process, material choice, or part geometry. contact us
