The spring washers supplied by YS STEEL are specialized engineering elastic anti-loosening fasteners. They are made of spring steel and are accompanied by a thermal treatment process. The open structure continuously provides axial elastic preload after the bolt is tightened, counteracting the torque attenuation caused by alternating loads and wind vibrations.
The manufacturer of YS STEEL performs a hot-dip galvanizing treatment on the entire China Spring washer. The coating
covers
the inner and outer surfaces of the gasket as well as the cut edges, suitable for long-term outdoor exposure
conditions.
The product complies with the GB/T93 standard and covers specifications from M6 to M20. It can be supplied
independently
or in combination with bolts, nuts, and flat washers to form a complete fastening component set, suitable for
various
overseas engineering projects.
Product Applications
- Photovoltaic power station projects
- Steel structure projects
- Greenhouse construction projects
- Outdoor construction machinery
- Exported complete fastening component kits
Differences and Advantages
1. The spring washers are produced using a full-piece zinc immersion process. The cut edges also form a protective
zinc
layer, different from ordinary post-zinc spraying products. This reduces the risk of premature rusting at the cut
edges and
meets the long-term outdoor usage requirements of photovoltaic and steel structure projects.
2. The thermal treatment parameters are adjusted according to outdoor vibration conditions, ensuring stable elastic
rebound and reducing the likelihood of permanent flattening failure under compression, thereby reducing the
frequency of
later inspection and maintenance.
3. The dimensional tolerances are strictly controlled, enabling the assembly of complete fastening component sets.
The
installation process is smooth and there are no problems such as jamming or improper assembly at the site.
4. Customization for projects is supported. Unless the standard size is specified, the thickness of the gasket and
the
opening parameters can be adjusted according to customer drawings, suitable for special structural nodes.
5. Flexible supply mode. Standard specifications are always in stock. Either the gasket can be purchased
independently or
the complete fastening component set can be packaged for export, simplifying the procurement process for overseas
customers.

FAQ
Q1: Can your company provide the Spring washer inspection report for project approval?
A1: Yes, corresponding quality inspection materials can be provided for each batch of products, and compliant
documents
can also be issued according to project requirements for overseas engineering approval.
Q2: What is the sample application process? Is the sample free of charge?
A2: Standard specifications can provide samples. The samples are free of charge, and the freight is borne by the
customer;
non-standard customized samples require a small sample processing fee.
Q3: What is the approximate regular delivery time for the in-stock products?
A3: Regularly stocked specifications will be arranged for shipment within 3-6 working days, and the production cycle
for
non-standard customized products is 7-14 working days.
Q4: Does the factory support customizing non-standard size spring washers according to customer drawings?
A4: Yes, engineers will first assess the drawing conditions and confirm the process feasibility before arranging
customized
production.
Q5: Can the bolts and nuts be packaged together as a complete fastening component for export?
A5: Supported. It can be combined and matched according to the project list, and unified export packaging can be
provided
to reduce the cost of multiple-category procurement coordination for customers.
Q6: If it is a large batch order, can a factory visit be arranged?
A6: Customers are welcome to visit the factory in person. If it is inconvenient to visit, real-time workshop videos
can be
provided for on-site viewing.
Q7: Can the product export packaging be printed with the customer's brand logo?
A7: Yes, it meets the OEM branding requirements. The outer packaging marks and labels can be customized according to
the
customer's requirements.
