Product Name
- Leister 100.814 -LOCK WASHER
Brief Description
- The Leister 100.814 Lock Washer is a specialized metallic fastener designed to prevent nuts and bolts from loosening due to vibration, torque, or thermal expansion. It serves as a critical replacement component for Leister hot air tools, ensuring the secure assembly and reliable operation of equipment.
Popular Applications & Uses
- Securing components within Leister hot air tools, such as the airflow and temperature control knob on models like the Hot Jet S.- Preventing fasteners from backing out in high-vibration environments, including engines, heavy machinery, and vehicles.- Maintaining joint stability in critical mechanical, automotive, and structural applications where secure and long-lasting fastening is essential.- Used in assemblies subject to dynamic loads or thermal expansion where fasteners might otherwise loosen.
Industries that Commonly Use It
- Construction/ Building Services (e.g., roofing, flooring applications with hot air tools)- Plastic Fabrication (e.g., plastic welding and processing)- General Manufacturing (for various assembly and repair tasks)- Industrial Supply (as a replacement part for specialized equipment)- Flooring Installer or Manufacturer- Tarp, Fabric, Awning Manufacturing- Automotive Service/Repair- Aerospace/Defense- Marine- Transportation/ Specialty Vehicle- Metal Fabrication
Special and Unique Features
- Engineered to resist loosening caused by vibration, dynamic loads, or thermal expansion.- Creates tension or friction within a bolted joint to maintain clamp force.- Specific design for compatibility and optimal performance within Leister brand hot air tools.- Contributes to enhanced safety and extended service life of mechanical assemblies by preventing fastener failure.
Key Properties
- Material: Typically made from metallic materials such as stainless steel, carbon steel, spring steel, aluminum, bronze, or phosphor bronze, sometimes with zinc plating for corrosion resistance.- Functionality: Works by elastic deformation, friction, or mechanical interlock to resist fastener rotation.- Types: Can come in various forms, including split, tooth (internal/external), wedge, and Belleville (conical) designs, each suited for specific applications and load conditions.- Durability: Designed to withstand tough environments and maintain integrity under stress.
Surface Compatibility
- Compatible with a wide range of material surfaces, including various metals and potentially soft plastics, by biting into the surface or creating constant tension to secure the fastener.- Effective when placed between the nut (or bolt head) and the surface of the part being fastened, ensuring direct contact for optimal friction and locking action.
Known backups / known substitutes
- Other types of lock washers (e.g., split lock washers, tooth lock washers, wedge lock washers, Belleville washers, tab washers).- Thread-locking compounds (e.g., liquid threadlockers).- Self-locking nuts (e.g., nylon insert lock nuts).- Double nutting.
Comparison Note
- Unlike standard flat washers, which primarily distribute load and protect surfaces, lock washers are specifically engineered with a geometry (split, curved, conical, or serrated) to actively resist loosening of fasteners under dynamic conditions. They achieve this by adding tension, friction, or a mechanical interlock to the joint, making them essential in applications where fastener security is paramount.
