The diameter and hexagonal/plan dimensions are separate drawing labels and are not interchangeable. Dimensions are transcribed from the supplied labels; no tolerances or thread pitches are specified.
The SEP base code identifies the height and hexagon dimension. The source uses a final square placeholder for the thread dimension. The tables retain the base code and show the thread separately so the complete requested configuration can be specified without assuming a suffix format.
Руководство по выбору
Select the base model by its height and hexagon dimension, then choose a listed thread configuration. SEP5046 lists only a 10 mm nominal thread diameter. SEP7060 lists 10, 12 and 16 mm configurations with different torque strength and thread depth values.
Информация для заказа
For a quotation, specify the SEP base model and listed nominal thread diameter, required quantity, thread form, insert material, insulating material and colour. Custom configurations for colour, inserts, material properties and threads can be requested.
