Product Name
Leister 100.816 - CHEESE HEAD SCREW M3 X 8
Brief Description
The Leister 100.816 is a metric M3x8 cheese head screw, specifically designed as a replacement part for Leister hot air tools, such as the Leister Hot Jet S. Cheese head screws are characterized by their cylindrical head, a flat top, and a flat bearing surface, often featuring a slotted drive. This design allows for controlled torque applications and is suitable for compact spaces.
Popular Applications & Uses
- Securing internal components within Leister hot air tools, like the Hot Jet S.- General fastening in electronics and electrical equipment, including circuit boards, switches, connectors, and electrical enclosures.- Assembly of small mechanical components in machinery and manufacturing, such as motors and gears.- Automotive applications for securing various internal and external components.- Precision fastening in compact spaces where a low-profile head is required to prevent interference with other components.- Applications requiring frequent disassembly where a robust drive socket is beneficial.
Industries that Commonly Use It
- General Manufacturing- Electrical Services or Products- LED/Electronics- Automotive Service/Repair- Plastic Fabrication- Construction/ Building Services (for equipment maintenance in roofing, flooring, civil engineering)- Distributers & Resellers- Industrial Supply- Engineering Services- Metal Fabrication- Packaging Services or Contractor (for equipment maintenance in shrink wrapping, film packaging)- Tarp, Fabric, Awning Manufacturing (for equipment maintenance)- Thermoforming (for equipment maintenance)- Cabinet & Woodworking (for general furniture and woodworking applications)- Aerospace/Defense (for Leister equipment maintenance)- Chemical Industry (for stainless steel variants in corrosive environments)
Special and Unique Features
- **Cheese Head Design:** Features cylindrical sides with a flat disc top and a flat bearing surface, which allows for even pressure distribution during installation and results in a low-profile finish.- **Deep Recess Capability:** The deep head design is well-suited for a slot drive, providing extra head strength and a deeper drive socket, which is advantageous for applications requiring frequent disassembly or where drive socket damage is a concern.- **Precision Metric Threading:** The M3 metric machine threads ensure a tight, secure, and vibration-resistant fit in tapped holes or when paired with corresponding nuts.- **OEM Compatibility:** As a genuine Leister part (100.816), it ensures perfect fit, compatibility, and optimal performance within specified Leister hot air tools like the Hot Jet S.
Key Properties
- **Material:** While the specific material for 100.816 is not detailed, cheese head screws are commonly made from steel, stainless steel (A2, A4 for corrosion resistance), brass (for electrical conductivity or aesthetics), or various plastics (for chemical resistance or insulation).- **Dimensions:** M3 (3mm nominal diameter) x 8mm length.- **Head Type:** Cheese head with a flat bearing surface and cylindrical sides.- **Drive Type:** Typically features a slotted drive, as seen in the product image and common for cheese head screws.- **Mechanical Strength:** Provides high tensile strength and dimensional accuracy for reliable fastening in mechanical assemblies.
Surface Compatibility
- Designed for secure fastening into pre-drilled and tapped holes in various materials, including metals, plastics, and wood, or for use with corresponding nuts in through-hole applications.- The broad, flat bearing surface of the cheese head helps distribute clamping force evenly, minimizing the risk of surface damage or deformation on the fastened material.- Compatibility with specific surface materials may depend on the screw's material composition (e.g., stainless steel for corrosive environments).
Known backups / known substitutes
- **Pan Head Screws:** Often used as a substitute in many applications, though cheese heads are preferred for their deeper slot capability and extra head strength.- **Fillister Head Screws (Raised Cheese Head Screws):** Similar to cheese heads with cylindrical sides and a flat mating surface, but feature a domed top, resulting in a deeper overall head.- **Countersunk Screws M3 x 8:** Another type of M3x8 screw, such as Leister 100.056, which is also a replacement part for the Hot Jet S, but designed for flush mounting with a conical head.- **Generic M3x8 Cheese Head Screws:** Available from various manufacturers, but may not offer the exact material specifications, quality, or guaranteed compatibility of an OEM Leister part.
Comparison Note
The Leister 100.816 cheese head screw, as an Original Equipment Manufacturer (OEM) replacement part, offers guaranteed compatibility and performance within Leister Hot Jet S tools, ensuring the integrity and longevity of the equipment. While generic M3x8 cheese head screws exist, they may not meet Leister's precise specifications or quality standards, potentially affecting tool performance or lifespan. Compared to pan head screws, cheese head screws provide a deeper slot for enhanced drive engagement and greater head strength, making them suitable for applications requiring robust fastening and potential frequent disassembly.
