Product Name
Leister 100.269 THREAD FORMING SCREW M4 X 8
Brief Description
The Leister 100.269 Thread Forming Screw M4 x 8 is a specialized fastener designed for creating secure, vibration-resistant connections in various materials, particularly plastics and light metals. It is specifically identified as a genuine replacement part for Leister hot air tools and plastic welding equipment, ensuring precise component alignment and reliable fastening within these industrial devices.
Popular Applications & Uses
- Fastening components within Leister hot air guns and plastic welding machines.- Securing parts in plastic fabrication and repair.- Assembly of electronic enclosures and automotive parts.- Applications in thin sheet metal, such as HVAC systems and ductwork.- General assembly where strong, self-formed threads are required in ductile materials.
Industries that Commonly Use It
- Plastic Fabrication- General Manufacturing- Construction/ Building Services (for roofing, flooring, civil engineering applications using Leister tools)- Automotive Service/Repair (for car wrapping, automotive part assembly)- Sign & Display (for plastic fabrication)- Tarp, Fabric, Awning Manufacturing (for welding tarps)- Flooring Installer or Manufacturer (for vinyl floor welding machines)- Distributers & Resellers (for selling replacement parts)- Industrial Supply (as a component for industrial equipment maintenance)
Special and Unique Features
- **Thread-Forming Design:** Creates its own mating threads by displacing material, eliminating the need for pre-tapped holes or nuts.- **Vibration Resistance:** The tight, gap-free fit formed by the screw significantly reduces the risk of loosening due to vibration.- **Optimized for Specific Materials:** Engineered to perform effectively in thermoplastics, some thermosets, and light metals, minimizing stress to the host material.- **Genuine Leister Part:** Ensures compatibility and optimal performance with Leister hot air tools and plastic welding equipment.- **M4 x 8mm Specification:** Standardized metric size for precise fit in designated applications.
Key Properties
- Material Displacement: Forms threads by compressing and deforming the host material, rather than cutting it.- High Pull-Out Force: Creates strong, secure connections with enhanced resistance to pull-out.- Low Driving Torque, High Stripping Torque: Designed for efficient installation while maintaining a strong hold.- Metric Sizing: M4 thread diameter, 8mm length.- Durability: Contributes to the longevity and reliability of the assembled components.
Surface Compatibility
- Plastics (thermoplastics and some thermosets)- Thin Composite Materials- Light Metals (e.g., Aluminum, Brass, Sheet Steel)- Ductile Steel
Known backups / known substitutes
- Generic M4 x 8mm thread-forming screws from other manufacturers, though compatibility and performance with Leister equipment may vary.- Standard machine screws with nuts, if the application allows for tapping and nut fastening, but this would negate the benefits of thread-forming.- Self-tapping screws, which cut rather than form threads, but may produce swarf and offer less vibration resistance.
Comparison Note
Unlike traditional self-tapping screws that cut material to create threads, the Leister 100.269 Thread Forming Screw M4 x 8 displaces and compresses the host material, resulting in a stronger, more vibration-resistant joint without producing swarf. Its design is optimized for specific material types, offering superior fastening efficiency and reliability, especially crucial for precision equipment like Leister hot air tools. While generic thread-forming screws exist, using the genuine Leister part ensures perfect fit, material compatibility, and maintains the integrity and performance of the original equipment.
