China Spring Washers Suppliers - Industrial Open Gasket Factory for Enhanced Bolt Performance

Spring washers are essential components in applications where the pre-tightening force of bolts is relatively low, and the dynamic loads are minimal. Designed to combat bolt stress relaxation, these washers are especially beneficial in situations where the clamping length of the bolt is short. By utilizing spring washers, users can effectively address issues related to bolt stability and performance. As a leading manufacturer and supplier in China, our factory produces high-quality spring washers that meet industry standards and ensure long-lasting reliability in various mechanical applications

Product Detail

The spring washer has good anti-loose effect and anti-seismic effect.

The general direction of the thread is right-handed, and the spiral direction of the spring washer is left-handed. After tightening the nut, the elastic reaction generated by the washer flattening compels the screw threads.

At the same time, when the fastener combination is subjected to the axial force of the vibration of the bolt, due to the elastic deformation of each part after the stress, sometimes there will be a gap between the fasteners, which is easier to loose.

The tip of the spring washer’s oblique mouth is against the supporting surface of the bolt or nut and the connected part, which can make up for the gap between the instantaneous fasteners and prevent loosening.

Frequently Asked Questions

Q: What are the primary benefits of using a spring washer?

A spring washer provides an excellent anti-loose effect and anti-seismic effect, securing fasteners against vibrations and external forces.

Q: How do the thread and spiral directions of the washer work?

Typically, the thread direction of the bolt is right-handed, while the spiral direction of the spring washer is left-handed to optimize the locking mechanism.

Q: What happens when the nut is tightened over a spring washer?

Once the nut is tightened, the spring washer flattens, generating an elastic reaction force that tightly compels and secures the screw threads.

Q: Why do fasteners loosen under vibration?

When subjected to the axial force of bolt vibration, the elastic deformation of the stressed parts can create temporary gaps between the fasteners, making them prone to loosening.

Q: How does the oblique mouth of the spring washer prevent loosening?

The tip of the spring washer's oblique mouth presses directly against the supporting surface of the bolt, nut, and connected part. This design compensates for instantaneous gaps and prevents the assembly from loosening.
