Product Name
Leister 100.284 THREAD FORMING SCREW M4 X 14
Brief Description
The Leister 100.284 THREAD FORMING SCREW M4 X 14 is a metric thread forming screw, specifically designed to create its own mating threads in various materials by displacing rather than cutting material. This process ensures a tight, secure, and vibration-resistant fastening. It functions as a crucial replacement part or accessory for Leister's extensive range of industrial hot air tools and plastic welding equipment.
Popular Applications & Uses
- Fastening internal components within Leister hot air tools and plastic welding machines.- General fastening applications in plastics, thin sheet metal, and lightweight alloys.- Used in electronic enclosures for secure assembly.- Automotive assembly and repairs, including parts and car wrapping applications.- HVAC systems and ductwork where durable threads are needed in thin metals.- Creating strong, reliable connections in precision machinery and equipment across various industrial sectors.
Industries that Commonly Use It
- Plastic Fabrication: Essential for assembling and maintaining plastic welding and processing equipment.- General Manufacturing: Utilized in the assembly of diverse products requiring robust fastening solutions.- Construction/ Building Services: Applied in areas like roofing, flooring, and geomembrane installation where Leister tools are prevalent.- Automotive Service/Repair: For securing components in vehicles and in processes like car wrapping.- Tarp, Fabric, Awning Manufacturing: Used in the maintenance of machines that weld tarps and industrial fabrics.- Industrial Supply: Distributed as a critical component for various industrial applications.- Distributers & Resellers: Sold through channels like Perigee Direct as a replacement part.- LED/Electronics: Ideal for securing components within electronic enclosures due to its thread-forming properties.- Aerospace/Defense: Employed in applications requiring secure and durable fastening.- Marine: Used for high-performance, corrosion-resistant fastening solutions in marine environments.
Special and Unique Features
- Self-threading capability: This screw forms its own threads in a pre-drilled or existing hole by displacing material rather than cutting it, thereby eliminating the need for a separate tapping operation.- Vibration resistance: By creating perfectly mated internal threads, it ensures a tight and secure fit, significantly reducing the likelihood of loosening due to vibration.- Optimized for Leister equipment: As a genuine Leister part, it is designed to ensure precise compatibility and optimal performance with Leister's specific hot air tools and plastic welding machinery, contributing to the integrity and longevity of the equipment.
Key Properties
- Type: Thread Forming Screw.- Dimensions: M4 (4mm nominal diameter) x 14mm (length), adhering to metric standards for precision applications.- Function: Primarily for secure fastening and precise component alignment within assemblies.- Material: Typically constructed from steel, often featuring a protective coating such as zinc plating for enhanced durability and corrosion resistance, though the specific material composition for this Leister part is not explicitly detailed in available information.
Surface Compatibility
- Plastics: Compatible with both thermoset and thermoplastic materials, making it suitable for a wide range of plastic assemblies.- Thin Sheet Metal: Effective in creating durable threads in thin metals, commonly found in applications like HVAC systems and ductwork.- Lightweight Alloys: Suitable for use in materials such as magnesium and aluminum, where it enhances pull-out force.- Wood: Can be used in wood applications, leveraging its thread-forming capabilities.
Known backups / known substitutes
- Other M4 x 14mm thread forming screws from alternative manufacturers (e.g., EJOT PT-Alternative, Aspen Fasteners, TR Fastenings) may serve as substitutes, provided they meet the necessary specifications and quality standards.- Standard machine screws, though these would necessitate pre-tapped holes, adding an extra manufacturing step.- Thread cutting screws, which cut material away rather than displacing it, potentially generating different stress profiles in the material.
Comparison Note
Leister's genuine 100.284 THREAD FORMING SCREW M4 X 14 is specifically engineered for optimal compatibility and performance within their hot air tools and plastic welding equipment. While generic M4 x 14mm thread forming screws might physically fit, they may not offer the same material quality, precise head design, or exact thread-forming characteristics that are optimized for Leister's applications. Using non-genuine parts could potentially impact the durability, reliability, and overall performance of the Leister machinery, making the genuine part the recommended choice for maintaining equipment integrity.
