Vg (valve thread)

Machine taps for Vg, valve threads

Valve threads sit on tyre valves and valve cores — a small series of its own, outside the usual standards. Machine taps cut the thread in a single pass and run in a drilling machine, a machining centre or a tapping attachment.

VÖLKEL offers 6 versions to DIN 374, in HSSE, from Vg 5 x 36 to Vg 12 x 26. The lead is in form C.
