- For producing high-strength screw connections and other threaded connections in materials with low shear strength, e.g. cast iron, aluminium alloys, plastics, hardwood etc.
- The inserts are simply screwed into a pre-drilled or pre-cast hole
- Cutting effect due to sharp edges and interrupted threads of the male thread
- The front threads are bevelled for easier cutting and insertion
- The cutting slot keeps the thread inserts anchored even during strong vibrations or shaking of the workpiece.
- Chrome(VI)-free zinc thick film passivation for good corrosion protection (corrosion resistance in salt spray test according to DIN EN ISO 9227-NSS (h): 72h white rust/120 red rust)
- Applications in the entire metal and plastic processing industry
- Thread reinforcement on tools with low shear strength, e.g. cast iron, aluminium alloys, plastics, hardwood etc.
- For repairing torn-out threads
- Usual applications:
- For light metals and metals with a strength up to approx. 400 N/mm²
- For cast iron with hardness up to approx. 220 HB
- Plastic and fibreglass-reinforced plastic
(Tests on the original component are recommended, particularly near edges.)
