METRIC HEX JAM NYLON LOCK NUT DIMENSIONS

Metric Hex Jam Nylon Lock Nut Dimensions Chart according to ISO 10511 standard.

Some important notes from the ISO standards:

- ISO 10511 specifies the characteristics of prevailing torque type hexagon thin nuts (with non-metallic insert) with thread from M3 up to and including M36, with product grade A for threads d ≤ M16 and product grade B for threads d > M16.

- Mechanical properties of ISO 10511 hex jam lock nuts: Steel - Property class 04 and 05.
