M12x1.5-6g in, every dimension out.
A designation is a prefix (M, MJ, or Tr), a nominal diameter, an optional pitch -- required for fine and trapezoidal sizes, assumed coarse for M/MJ otherwise -- and, for M and MJ, an optional tolerance class: a grade digit for how wide the tolerance zone is, and a letter for how far it sits from the basic size. Type any of it below.
MØ12 mmP 1.5 mm6g
Small allowance -- the common general-purpose external class.
Try “M12x1.5-6g”, “M8” (coarse pitch assumed), “MJ6-4h6h”, or “Tr20x4-8H”. Add “-LH” for a left-hand thread.
