DIN 961

DIN 961 - Hexagon head screws with fine pitch thread up to the head - Product grades A and B

Automatically build standard products in SOLIDWORKS with TSFP.

Outdated standard

Withdrawn German predecessor of ISO 8676 with fine metric thread nearly to the head and older spanner sizes at M10, M12, M14 and M22. DIN 961:1990-01 permits a near-head shank diameter approximately equal to the thread pitch diameter.
