VIS M14X50 8,8

M14x50 Class 8.8 ISO 4014 / DIN 931 screw for agricultural mounting

Ref. number: CAM194928

In haymaking equipment, the quality of the fasteners plays an essential role in ensuring the resistance of components subjected to repeated vibration and shock. This M14x50 class 8.8 screw is specially designed for demanding mechanical assemblies, in particular for fastening KUHN tedder tines.

Robust, reliable and compliant with current standards, it is ideally suited to assemblies exposed to dynamic stress on tedders, windrowers and other powered implements.

Technical specifications

• Thread diameter: M14

• Screw pitch: 2.00 mm

• Overall length: 50 mm (measured under head)

• Threaded length (b): 34 mm

• Head type: Hexagonal

• Key size: 21 mm / 22 mm (to ISO tolerance)

• Head height (k): 8.8 mm

• Strength class: 8.8

• Material: Steel

• Surface treatment: Zinc-plated

• Standards: DIN 931 / ISO 4014

ISO 4014 replaces DIN 931, with a corresponding wrench size for certain diameters. For M14, the standard wrench is generally 21 mm, but some products are available in 22 mm.

Use in haymaking equipment

This M14x50 screw is used in particular for :

• KUHN tedder tine attachment ref. 58740700

• KUHN tedder tine attachment ref. 58740600

Tines on tedders are subject to heavy stress: rapid rotation, contact with forage, constant vibration. An inferior quality screw can lead to loosening, tearing or premature wear of the support.

Class 8.8 guarantees good mechanical resistance to traction and shearing, adapted to current agricultural stresses.

Advantages of this M14x50 screw

• High mechanical strength (class 8.8)

• Precise metric thread for reliable tightening

• Anti-corrosion protection thanks to zinc plating

• Suitable for mounting on KUHN tedder tines

• Complies with ISO / DIN industrial standards

Mounting tips

For optimum fastening:

• Check the condition of the support threads

• Use a nut of equivalent class (8 minimum)

• Observe recommended tightening torque for M14 class 8.8

• Check tightening after the first few hours of use

In haymaking, regular checking of fasteners avoids loss of parts in the field and unforeseen stoppages.
