Lengths above 400 mm shall be graded in 20 mm steps. Bracketed sizes should be avoided if possible. T-head bolts are normally manufactured in sizes for which shank lengths have been specified.
lg max. = l (nominal lengths) - b (auxiliary size) shall apply for screws with lengths below the stepped line;
ls min. = lg max. - 5 P.

4 Designation
Designation of an M 20 T-head bolt, of nominal length l = 120 mm:
T-head bolt DIN 261 — M 20 × 120
Normally, the internal thread diameter, db, is to be specified for T-head bolts exceeding a mass of 10 kg and shall be particularly agreed upon when ordering. The designation shall then read, e.g.:
T-head bolt DIN 261 — M 72 × 6 × 400 × M 16
