Specification

Nuts with reduced load capacity

Hexagon nuts with lower nominal height complying with the withdrawn DIN 985 standard cannot support test loads as per DIN EN ISO 20898-2

The strength class designation has two vertical bars added before and after the strength code for differentiation.

DIN 985 has been replaced by ISO 10511, 10512 and 7040

When the screw-nut connection is established, the screw thread is secured by the plastic ring. The high level of friction created by the clamping forces between the thread profiles generates the locking torque necessary to maintain the pre-load force.

No damage to the thread surfaces

Operating temperature range: -70 °C to +120 °C

When using a nut and screw of the same size, the difference between strength class I8I and I10I is a greater load capacity of approximately 40 %

Notice

Hexagon nuts with lower nominal height complying with DIN 985 cannot support test loads as per ISO 898-2

The strength class designation has two vertical bars added before and after the strength code for differentiation.

DIN 985 has been withdrawn and replaced by ISO 10511. There is some limited similarity (thread M7, M18, M22, M27, M33 and threads with nominal dia. > M36 removed | Fine thread removed | Nut height changed | Width across flats changed for threads M10, M12 and M14 to 16, 18 and 21 mm | Strength classes changed to 04 and 05).
