Product Overview
Product Application
DIN 9250 VS is a heavy type double-sided serrated lock washer designed to prevent bolt loosening under vibration and dynamic loads. Compared with standard spring washers, DIN 9250 VS provides higher locking performance through its double-sided radial serration structure, creating a strong mechanical grip between the bolt head/nut and the mating surface.
It is widely used in automotive, mechanical equipment, construction machinery, railway, and industrial assembly applications where reliable fastening security is required.
Draw
Specification
DIN 9250 VS vs Standard Spring Washer
DIN 9250 VS
- Double-sided serrated locking structure
- Higher resistance to vibration loosening
- Better preload retention
- Designed for heavy-duty applications
Standard Spring Washer (DIN 127)
- Helical spring structure
- Mainly provides elastic tension
- Lower locking performance under severe vibration
For critical bolted joints exposed to vibration, DIN 9250 VS offers a more reliable locking solution.
Product Advantages
Higher Load Capacity
The heavy series design offers greater thickness and stiffness compared with standard serrated washers, making it suitable for higher-strength bolted joints.
Reusable Locking Performance
When properly installed, DIN 9250 VS can maintain effective locking performance during maintenance and repeated assembly operations.
Common Questions
What is DIN 9250 VS?
DIN 9250 VS is a heavy-duty double-sided serrated safety lock washer designed to prevent bolts and nuts from loosening caused by vibration and dynamic loads.
What is the difference between DIN 9250 S and VS?
DIN 9250 S is the standard type, while DIN 9250 VS is the heavy type with increased thickness and stronger locking capability. VS is typically used for higher load applications.
Which bolts are suitable with DIN 9250 VS?
DIN 9250 VS is commonly used with metric bolts including DIN 931, DIN 933, ISO 4014, and ISO 4017 bolts.
