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.
Selection Guide
Choose the base model by its height and hexagon dimension, then select a listed nominal thread diameter. The torque strength and thread depth must follow the same configuration row. SEP3532 and SEP3541 have different thread depths between their 6 mm and 8/10 mm configurations.
Ordering Information
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.
