SEMS screws, also known as SEM screws, are machine screws with a washer or washers permanently attached to them. The washer is fastened to the bolt before the threads are machined, ensuring it remains securely in place and cannot fall off. This integrated design simplifies assembly processes and enhances reliability. SEMS screws are also referred to as captivated washers, screw/bolt-washer assemblies, or combi bolts.
Permanently Attached Washers: The washer or washers are securely fastened to the screw before threading, preventing them from coming loose and ensuring consistent assembly.
Simplified Assembly: Combining the screw and washer into a single unit streamlines the assembly process, reducing handling and installation time.
Machine Screw Threads: Precision threading ensures secure and reliable fastening in various applications.
Applications of SEMS Screws:
Electronics: Ideal for securing electronic components, providing a reliable and streamlined fastening solution in electronic devices and assemblies.
Automotive: Commonly used in automotive manufacturing and repair, offering efficient and dependable fastening for various components.
Industrial Machinery: Suitable for use in industrial equipment, ensuring secure connections that withstand operational stress and vibrations.
Appliances: Used in the assembly and maintenance of household and industrial appliances, providing secure and efficient fastening.
General Assembly: Versatile enough for a wide range of general-purpose fastening tasks where an integrated screw and washer solution is beneficial.
Benefits of SEMS Screws:
Increased Efficiency: The integrated design of SEMS screws reduces the number of loose parts, simplifying inventory management and speeding up the assembly process.
Enhanced Reliability: The permanently attached washer ensures consistent performance and prevents the washer from slipping or misaligning during installation.
Versatility: Suitable for a wide range of applications, from electronics to industrial machinery, offering flexibility in various assembly processes.
Durability: Made from high-quality materials, SEMS screws provide long-lasting performance and resistance to wear and corrosion.
