DIN 976-1 Standard Dimensions for Stud bolts, metric thread
Stud bolts - Part 1: Metric thread
This standard (DIN 976) specifies dimensions and technical delivery conditions for stud bolts with metric thread made of steel, stainless steel or nonferrous metal.
Stud Bolts with metric thread are designed to perform functions similar to those of double end studs (clamping type or interference-fit type). This standard covers stud bolts with threads produced to tolerance 6g which is customary for bolt/nut assemblies of thread engagement group N as specified in DIN ISO 965-1. Attention is drawn to the fact that stud bolts with lengths exceeding those specified for thread engagement group N might not be true to gauge.
