Most buyers tell us their customers are installing these on heavy-duty horse fencing — teh kind that takes constant weather and impact, so they really need the washer to hold tight without loosening over time.
We've been making these for years, and what it does is combine a flat and spring washer into one unit, saving assembly time, and our company can customize the structure to match your design — just send us the drawing, usually 2-3 iterations to get it right.

Bulk pricing depends on quantiy, obviously, but for a 20-foot container order we're typically around 0.03 to 0.05 USD per piece, give or take, though lead time is roughly 25-30 days after sample approval (check MOQ for custom sizes).

Also, most buyers go with 304 stainles for the corrosion resistnce, but we've had some ask about 316 for marine environments — it's pricier but worth it if salt spray is an issue.

Originally they're for equestrian fencing, but we've seen them used in greenhouse frames and even heavy-duty chicken coops, basically anywhere you need a firm connection that won't rattle loose.
You'll get COA with each batch showing hardness and tensile, and packaging we usually do is plastic bags inside cartons on pallets, but we can do custom labeling if your brand requires it.
We can make them in 304, 316, or other stainless steel grades depending on your needs. Just let us know the specific grade you require for your equestrian fencing setup.
Our MOQ typically starts at 5,000 pieces for standard sizes, but we can discuss smaller quantities if you're running a trial. Custom specs might adjust that number a bit.
Yes, we can supply a mill test certificate or chemical composition report for each batch. Just request it when placing your order.
They come in plastic bags inside cartons, stacked on pallets and stretch-wrapped. We can also customize the packaging if your handling or storage setup requires it.
For a custom size, lead time is usually around 15 to 25 working days after order confirmation, depending on quantity and current production load. We'll give you a firm date once we finalize the specs.
