Machine taps with yellow ring
The yellow ring marks a version of its own within the coloured-ring programme and keeps it apart from its same-sized neighbours on the shelf. The coloured ring on the shank identifies the version at a glance, without reading the marking — useful when several variants of the same size sit side by side on the shelf.
VÖLKEL offers 20 versions to DIN 371 and DIN 376, in HSSE, from M 3 x 0.5 to M 30 x 3.5, plus UNC 1/4 x 20 to UNC 1/2 x 13. The lead is in form C.
