DIN 976-2:2016-09

Stud bolts according to this standard are used, in the manner of studs, for screwing into components made of light metal (including aluminum); stud bolts according to this standard are not suitable for screwing into steel or cast iron. For economic reasons, it is recommended that, instead of studs with a very small unthreaded portion, stud bolts with an interference-fit thread be used for such applications. However, care shall be taken that the required depth of thread engagement is ensured, since stud bolts are not provided with a thread run-out, which normally determines the depth of thread engagement. It cannot be assumed with certainty that stud bolts with lengths exceeding those specified for the lengths of engagement in DIN 8141-1 are true to gauge. This standard has been prepared by NA 067-00-08 AA "Verbindungselemente mit Sonderformen und aus Kunststoff" ("Fasteners with special elements and made of plastic") at DIN Standards Committee Fasteners (FMV).
