The Tan β of helix angle for cutter is calculated via the following formula: pitch where Tan β = π(nominal T + nominal E) 2 T E is the thread diameter; is the wall diameter of threaded finish. The average of the maximum and minimum of "L" diameter is as close as possible to "L" nominal. The mean diameter diameter max + diameter min L is in the tolerance of ± 0,2 mm. 2 Optional: depressed thread at mould parting line (see EN 16292). 5
