METRIC HEX FLANGE LOCK NUT (WITH NYLON INSERT) DIMENSIONS

Dimensions of metric hex flange lock nuts (with nylon insert) are shown in the following chart according to ISO 7043 and ISO 12125 standards.

Some important notes from the ISO standards about hex flange lock nuts with nylon insert:

- ISO 7043 specifies the characteristics of prevailing torque type hexagon nuts with flange (with non-metallic insert) with threads from M5 to M20 inclusive, with product grade A for threads d ≤ M16 and product grade B for threads d > M16.

- Mechanical properties of ISO 7043 hex flange lock nuts: Steel - Property class 8, 9 and 10.

- ISO 12125 specifies the characteristics of prevailing torque type hexagon nuts with flange (with non-metallic insert) with metric fine pitch thread with nominal thread diameters d from 8 mm up to and including 20 mm, with product grade A for threads d ≤ M16 and product grade B for threads d > M16.

- Mechanical properties of ISO 12125 hex flange lock nuts: Steel - Property class 6, 8 and 10.
