Tolerances for Moulded Round Rods
The table below shows the dimensional tolerances permitted on moulded round rods. These tolerances are based on the relevant British Standads or BS EN Standards.
Tufnol Round Rods are normally supplied with a ground outside diameter.
All sizes and tolerances quoted are in millimeters.
Dimensional tolerances specified are PLUS AND MINUS from the nominal size.
