Q: What are the specific dimensional and mechanical standards for this half-thread bolt?
The bolt conforms to ISO 4014 (partial thread) and the nut to ISO 4032 . Property class is 8.8U , with "U" indicating 6az thread tolerance before hot-dip galvanizing to ensure final fit after coating.
Q: Why specify a half-thread design for non-preloaded connections?
The unthreaded shank provides a larger cross-sectional area through the joint's shear planes. This results in higher shear resistance and stiffness compared to the threaded portion, optimizing load capacity for static shear applications.
Q: What certification and marking are required for compliance?
The bolt head must be marked with "SB" , property class 8.8 , and a batch traceability code . The assembly must bear the CE mark under hEN 15048-1 and be supplied with a batch-specific 3.1 inspection certificate (EN 10204). Washers, if required, are ordered separately to ISO 7089
