DIN 938 standard
specifies dimensions and technical delivery conditions of studs intended for use
mainly in stainless steel, carbon steel and alloy steel with a comparatively lower
demand in brass as well. Din 938 Double End Stud Bolts have a thread length
engagement equal to 1d on stud end and the nut end length varies as per the
application. Double End Stud bolts can be manufactured as per DIN 938
Specification with metric thread M3 to M52 and metric fine thread M8x1 to
M52x3. As specified in DIN 267-2, the tap end studs shall be produced to tolerance
Sk6 as in DIN 13-51, unless the stud is designated without interference - Fit Thread
(Fo) or Sn4.
When ordering DIN 938 double end studs, the correct dimension is diameter x
nominal length (excluding the tap end b1).
For example, with a stud measuring M10X75 (the diameter(d) = 10mm and nominal
length(l) = 75 mm where the thread length on the metal end (tap end) b1 = 10 mm; the
overall length of the stud is 75 + 10 = 85 mm. The thread length on the nut end b2
varies depending on the length of the stud.
