This combination usually consists of a double-ended screw (male thread on one end and female thread on the other), a nut and a flat spring washer. The double-ended screw can be easily installed and removed from either end, while the flat spring washer provides additional elastic support and tightening force to prevent loosening of the screw or nut due to vibration or shock.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
Increased tightening force: Flat spring washers provide additional tightening force when compressed, increasing the friction between the bolt and the nut and preventing loosening. Anti-loosening effect: The design of the spring washer creates a preload during tightening, which helps to maintain the stability of the connection and prevents loosening even under vibration or dynamic loads. Quick Installation: The design of the double head screws allows installation and removal from both ends, which is useful where space is limited or quick assembly is required. Durability: The fasteners in this combination are typically made of durable materials such as stainless steel or carbon steel that can withstand repeated use and high loads .
Scope of Application
Mechanical connections in vibrating environments: In automobiles, mechanical equipment, home appliances, and other applications where fasteners need to be prevented from loosening, this combination can provide additional tightening force and anti-loosening effect. Frequent disassembly and assembly applications: In applications that require frequent disassembly and assembly, such as certain repair or maintenance work, double head screws can provide quick installation and removal. Applications requiring quick installation: Where quick installation or emergency repairs are required, double head screws can simplify the installation process and save time.
