What are SEMs Screws?
SEMS, an abbreviation for “pre-assembled washer screws,” are a type of combination screws, featuring a permanently attached washer / washers beneath the screw head. The washer serves multiple purposes, such as distributing load, preventing damage to surfaces, and providing a larger bearing surface for improved stability. This pre-assembled design streamlines the assembly process, making it faster and more convenient for manufacturers.
Applications of LFS SEMS Screws:
SEMS screws are value engineered fasteners suitable for various applications. Here are some common uses:
- Electronics and Electrical Equipment: SEMS screws are widely used in the electronics industry for securing components on circuit boards. The pre-assembled washer provides stability and prevents over-tightening, safeguarding delicate electronics.
- Automotive Industry: In automotive manufacturing, SEMS screws find application in securing components where vibration resistance and load distribution are crucial. They are commonly used in assembling interior components, dashboards, and electrical systems.
- Appliance Manufacturing: SEMS screws play a vital role in the assembly of household appliances such as refrigerators, washing machines, and ovens. The combination of a washer and screw simplifies the assembly process while ensuring a secure and long-lasting connection.
