High-Quality 1/2 Inch Spring Washer from China Suppliers & Factory – ANSI Open Gasket Spring Pad Mesons
The spring washer has good anti-loose effect and anti-seismic effect.
Thread & Spiral Direction
The general direction of the thread is right-handed, and the spiral direction of the spring washer is left-handed.
Elastic Reaction
After tightening the nut, the elastic reaction generated by the washer flattening compels the screw threads.
Vibration & Gap Mitigation
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.
Oblique Mouth Design
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
What are the primary functions of a spring washer?
The spring washer provides a highly effective anti-loose and anti-seismic mechanism for fastener combinations.
How do the thread direction and the spring washer's spiral direction align?
Generally, the thread direction is right-handed, whereas the spiral direction of the spring washer is left-handed.
What happens when the nut is tightened over a spring washer?
Once the nut is tightened, the washer flattens and generates an elastic reaction that directly compels the screw threads to stay secure.
Why do fasteners become loose under vibration?
When subjected to the axial force of bolt vibration, the elastic deformation of the stressed parts can create temporary gaps between fasteners, making them prone to loosening.
How does the oblique mouth of the spring washer prevent loosening?
The tip of the spring washer's oblique mouth presses firmly against the supporting surface of the bolt, nut, or connected part. This compensates for instantaneous gaps and effectively prevents loosening.
