High Quality 1 Inch Spring Washer - Durable Steel ANSI Gasket from China Suppliers & Factory
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.
Key Mechanism
The core anti-loosening mechanism relies on the left-handed spiral direction working against the standard right-handed thread, combined with the elastic reaction force that compensates for gaps caused by operational vibrations.
Anti-Seismic Design
Delivers excellent anti-loose and anti-seismic performance under heavy dynamic loads.
Opposing Spirals
Features a left-handed spiral direction to counteract standard right-handed threads.
Elastic Reaction
Flattening the washer creates continuous tension, compelling the screw threads together.
Gap Compensation
The oblique mouth tip presses against surfaces to instantly bridge vibration-induced gaps.
Frequently Asked Questions
What are the primary benefits of using a spring washer?
Spring washers provide excellent anti-loose and anti-seismic effects, making them highly effective in securing bolted joints subject to vibrations.
How does the spiral direction of a spring washer prevent loosening?
While standard bolt threads are right-handed, the spring washer features a left-handed spiral direction. This opposing direction helps resist rotational loosening forces.
What happens when the nut is tightened over the washer?
Tightening the nut flattens the spring washer, which generates an elastic reaction force. This continuous tension tightly compels the screw threads together.
Why do bolted connections loosen under vibration?
Vibrations subject bolts to axial forces. This causes elastic deformation in the joint components, creating temporary gaps that make it easier for fasteners to loosen.
How does the oblique mouth of the spring washer work?
The tip of the spring washer's oblique mouth presses firmly against the supporting surface of the nut or bolt. This physical contact compensates for instantaneous gaps and prevents rotation.
