Internal Corner Radius≥ 0.5 mm
Threaded Holes (Ø1.5–5 mm)M1.6–M5, depth ≤ 2 × diameter
Threaded Holes (≥ Ø 5 mm)M6 or larger; blind or through holes available
Text / EngravingText height ≥ 1 mm, depth ≤ 0.5 mm
Hole DesignHole diameter ≥ wall thickness; stepped holes recommended for deep holes
Wall ThicknessMetals ≥ 0.5 mm; plastics ≥ 1 mm
