Thick Steel Washers
Dimensional tolerance ： ±0.2mm
Weight : 0.5g-500kg
A notable increase in thickness is the fundamental characteristic of thick steel washers. Typically, it is thicker than 10 mm. Because of this, its pressure-bearing area is significantly greater than that of standard washers. The bolt preload force can be spread by over 50%. For heavy-duty connection points, this offers strong support. For instance, large steel equipment bases and structures.
It is also composed of premium steel that has been heat-treated for tempering and quenching. Surface hardness can consistently rise above HRC 28. By using high-strength bolts of grade 10.9 and higher, this guarantees strength matching. Hot-dip galvanizing is one method of treating it in harsh environments. Over 720 hours of salt spray protection are provided by its anti-corrosion coating. In humid industrial settings, this greatly increases service life and dependability.

Drawing Design & Confirm
Obtain drawings from customers or create drawings using their specifications or samples.
Both parties attest to the drawings, product raw materials, surface treatment, and other details.
Why choose us
Superb carrying capacity
Steel washers with a thickness of more than 10 mm are possible. Compared to the 1-3 mm thickness of regular washers, this is significantly thicker. Significant pressure-bearing area is provided by the increased thickness.
The preload force of the bolt can be distributed by over 50%. This can successfully stop the connected parts' surfaces from being crushed. In crucial connections like heavy steel structures, this feature is essential.
Excellent wear resistance
High-grade medium carbon steel or alloy steel are frequently used to make thick washers. It has an extremely high surface hardness. It can serve as a piece of sacrifice to safeguard the parent material. For instance, it shields components made of softer aluminum alloys.
In the process of tightening and working, this keeps the bolt head from scratching or getting embedded in the parent material. The more costly workpieces are shielded in this way.
Optimized surface treatment
A more stable foundation for surface treatment is offered by thick washers. For instance, the thick substrate can tolerate the process thermal stress when hot-dip galvanizing ≥50μm. It improves coating adhesion and prevents deformation.
According to tests, its coating's effective anti-corrosion life can be increased by roughly 40% when compared to thin gaskets in the same environment.
Matching high strength bolts
Ordinary thin washers may deform first when using high-strength bolts of grade 8.8 and higher. Thick steel washers have a load-bearing capacity comparable to grade 10.9 bolts. Typically, its hardness is higher than HRC 28.
This guarantees that the connection system's strength is balanced. High-strength bolts can reach their full potential. It is possible to increase the system's overall safety factor by roughly 15%.
Benefits
-
Provide reliable protection
- Composed of steel with a medium carbon content. The hardness of the surface is extremely high. It may be utilized as a piece of sacrifice. effectively shield the surface of the base material. keeps soft materials like aluminum from being scratched by bolt heads. greatly increase the main structure's service life.
-
Matching high-strength connections
- The hardness may be as high as HRC 28. Its capacity to support loads is exactly equal to that of grade 10.9 bolts. Steer clear of becoming the system's weakest link. Make sure you can fully utilize the performance of high-strength bolts. Boost the overall dependability of the connection.
-
Cushioning vibration shock
- The gasket's thickness allows for elastic compensation. 15% of the dynamic load energy can be absorbed. Reduce fretting wear at connections in an efficient manner. greatly lowers the possibility of vibration-induced bolt loosening. Boost the stability of the connection.

◆ ◆ ◆ F A Q ◆ ◆ ◆
What is the minimum order quantity? Can I have mixed batches?
- Our regular models usually have a minimum order quantity of 50kg or 1000 pieces. Special specifications may require separate negotiation. Different types of washers can be combined to calculate the total weight to reach the minimum order quantity, which is convenient for you to purchase together.
How long does the delivery usually take? Can it be expedited?
- Regular materials and surface treatments can be shipped in 3-5 days when stock is sufficient. Special processing or customized sizes generally take 7-15 working days. If there is indeed an urgent need, we can expedite the request, but a small additional fee may be incurred.
Can you provide samples? Is there any charge?
- Regular models can provide 1-3 samples for free, and you need to bear the express fee. Customized samples usually incur a cost fee, which can be deducted from subsequent formal orders.
What should I do if there are quality problems with the goods?
- Please provide feedback and provide photos and other evidence within 7 working days after receiving the goods. After confirming that it is our responsibility, we will arrange replenishment or negotiate a refund, and bear the relevant return and exchange freight charges.
What is the packaging like?
- Standard packaging is a carton or woven bag lined with anti-rust paper. Export standards will use vacuum packaging or anti-rust oil treatment. If you have special packaging requirements (such as labeling, pallets), please inform us in advance.
Can non-standard sizes or special coatings be customized?
- Can. Please provide detailed drawings and technical requirements. Customization requires separate mold opening or process adjustment, so there will be certain minimum order quantity requirements, and the delivery time and unit price also need to be recalculated.
Is it in stock? When can it be shipped?
- Regularly galvanized and blackened thick washers are available in some specifications. Specific inventory status needs to be checked in real time. After confirming the order and receiving payment, delivery can usually be arranged within 24 hours if the goods are in stock.
