Tolerance class ISO 228 + 0.05 mm.
Tolerance class ISO 228 + 0.05 mm.
Application:
For Whitworth parallel pipe threads DIN-ISO 228/1 (threads that do not form a seal within the connection).
For components which are galvanised, or shrink slightly when hardened.
For components which are galvanised, or shrink slightly when hardened.
Recommendation:
We recommend deviating from the DIN data (see table) by drilling the tapping hole ⌀ 0.05mm larger.
