High Quality 3/8 Inch Spring Washer - China Factory Suppliers for ANSI Open Gasket Spring Pads
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.
Anti-Loose & Anti-Seismic
Delivers exceptional resistance to vibration and loosening under high-stress conditions.
Opposing Thread Design
Features a left-handed spiral direction to counteract standard right-handed thread systems.
Elastic Gap Compensation
The oblique mouth design compensates for instantaneous gaps caused by axial vibration.
Frequently Asked Questions
What are the primary benefits of using a spring washer?
The spring washer provides excellent anti-loose and anti-seismic effects, helping to keep fasteners secure in environments prone to vibration.
How does the thread direction of a spring washer prevent loosening?
While the standard thread direction of a bolt is right-handed, the spring washer features a left-handed spiral direction, which physically counteracts the loosening direction of the nut.
What role does the elastic reaction play in fastening?
Once the nut is tightened, the spring washer is flattened. This creates an elastic reaction that continuously exerts force against the screw threads to maintain tension.
Why do fasteners loosen under vibration?
When a fastener combination is subjected to the axial force of bolt vibration, the individual parts undergo elastic deformation under stress, occasionally forming temporary gaps that lead to loosening.
How does the oblique mouth of the spring washer work?
The tip of the spring washer's oblique mouth presses directly against the supporting surface of the bolt or nut and the connected part. This design fills the instantaneous gaps created by vibration and prevents loosening.
