Product Name
Leister 100.057 - COUNTERSUNK SCREW M1.6 X 5
Brief Description
This product is a Leister 100.057 countersunk screw, specifically an M1.6 x 5 precision machine screw. It features a tapered head designed to sit flush with or below the surface of the material, ensuring a smooth and snag-free finish. This particular screw is identified as a replacement component for Leister hot air tools, such as the Hot Jet S.
Popular Applications & Uses
- Fastening internal components within Leister hot air tools, including models like the Hot Jet S.- Precision assembly in various electronic devices, such as consumer electronics (e.g., smartphones, tablets, laptops), computer technologies, and telecommunications equipment.- Securing delicate parts in medical devices, including diagnostic tools, hearing aids, and other intricate mechanical assemblies where high precision is critical.- Used in automotive components and assemblies to ensure smooth surfaces and maintain aerodynamic profiles.- Fastening applications in aerospace assemblies where a flush finish is essential for both aesthetics and functionality.- Assembly of optical devices, cameras, eyewear, and watches, requiring miniature and precise fasteners.- General fastening in manufacturing processes where a clean, low-profile, and snag-free surface is required.
Industries that Commonly Use It
- Aerospace/Defense- Transportation/Specialty Vehicle- LED/Electronics- General Manufacturing- Medical Device/ Prosthetics- Plastic Fabrication- Distributers & Resellers- Industrial Supply- Engineering Services
Special and Unique Features
- **Countersunk Head Design:** Engineered to allow the screw head to sit flush with or below the surface of the material, providing a clean, aesthetic, and snag-free finish.- **M1.6 Thread Size:** Denotes a micro or miniature screw, making it ideal for precision fastening in extremely tight spaces and delicate applications where standard fasteners are too large.- **High Precision Fastening:** Crucial for maintaining stability and preventing system failure in high-precision environments where even slight variations can impact performance.- **Leister Original Equipment Manufacturer (OEM) Part:** Ensures exact compatibility, material quality, and performance as specified by Leister for their specialized hot air equipment.
Key Properties
- **Material:** Commonly manufactured from durable materials such as stainless steel (e.g., A2-70 G304 for corrosion resistance), brass, or steel, depending on specific application requirements.- **Thread Type:** Machine screw with uniform, full threading, designed for use with pre-tapped holes or nuts.- **Head Type:** Countersunk (also known as Flat Head), with a 90-degree conical underside.- **Drive Type:** Typically features a Phillips drive, allowing for efficient torque application with standard cross-head screwdrivers.- **Dimensions:** M1.6 (1.6mm) nominal diameter with a 5mm length.- **Corrosion Protection:** Stainless steel variants (A2, A4) offer excellent corrosion resistance, suitable for various environments.
Surface Compatibility
- Designed for secure fastening into pre-tapped holes or through-holes when used with a nut.- Compatible with a range of materials including plastics, metals, and composites, particularly where a flush surface is desired.- Ideal for applications where the fastener must not protrude, preventing obstruction in assemblies with moving parts or ensuring a smooth exterior.
Known backups / known substitutes
- Generic M1.6 x 5 countersunk machine screws from other precision fastener manufacturers, provided they precisely match the thread pitch, head dimensions, material grade, and drive type.- Screws with similar dimensions but alternative head types (e.g., pan head) may serve as substitutes if a flush finish is not a critical requirement and space permits.- Fasteners with different drive types (e.g., Slotted, Torx) can be used if the appropriate driving tools are available and compatibility is ensured.
Comparison Note
The Leister 100.057 is an Original Equipment Manufacturer (OEM) part, specifically engineered to meet the exact specifications and quality standards of Leister's hot air tools. This ensures optimal fit, material integrity, and reliable performance within the intended equipment. While generic substitutes are available, they may vary in manufacturing tolerances, material composition, and drive quality, potentially compromising the longevity, precision, and overall functionality of the assembly, especially in sensitive or high-performance applications like professional plastic welding tools.
