Description
Overview
DIN439 specifies the standard dimensions for half nuts, ensuring compatibility with matching metric fasteners.
This selected size is specified with thread M24.
Sold in multiples of '1 pieces. 1 Box = '1 pieces.
Material, Grade & Strength
Select the material and property class to match the mating fastener, clamp load and corrosion environment.
Finish & Corrosion Protection
Choose the finish according to the installation environment and expected corrosion exposure.
Typical Uses
Used throughout machinery, fabrication, mining, agriculture, construction and maintenance with compatible bolts, screws, studs or threaded rod.
Technical Tips
- Match thread size and pitch.
- Use compatible property classes.
- Consider locking methods where vibration is present.
