- ATTENTION: when ordering studs according to this DIN standard the proper designation is d x L,e.g. stud M10X70 - DIN 938, where the working length L = 70 mm and the thread length on the metal end bm = 10 mm. The overall length of the stud is 70 + 10 = 80 mm. The thread length on the nut end b= 26 mm.
- The thread tolerance class on the metal end is Sk6 according to DIN 13-51, meaning "transition fit", which prevents loosening of the metal end of the studs during disassembly.
- In case this transition fit is not wanted, add "Fo" in the designation. These studs have thread tolerance class 6g on both ends and can be supplied as specials.
- Studs according to DIN 938 with a metal end ≈1d have many applications, but are mainly intended for use in steel counterparts.
