Tolerances for Moulded Round Rods




(Click here for Tolerances on Sheets.)
(Click here for Tolerances on Tubes.)

The table below shows the dimensional tolerances permitted on moulded round rods. These tolerances based on the relevant British Standards or BS EN Standards.

Tufnol Round Rods are normally supplied with a ground outside diameter.

All sizes and tolerances quoted are in millimetres.

Dimensional tolerances specified are PLUS AND MINUS from the nominal size.
