Dual Acting Double Ended Self Locking Washer

If you buy dual acting double ended self locking washers in large amounts, most suppliers will give you a discount—and the more you order, the cheaper they get. Order 5,000, and you might get 5% off—order over 20,000, and the discount could go up to 10 or 15 percent.

This is the core reason why factories prefer bulk purchases, especially for these frequently used washing machines. Even more attractive is that some suppliers waive minimum order quantities for returning customers – a policy that makes it easy for even smaller stores to enjoy the benefits of bulk purchases.

You can check the discount tiers on the supplier’s website or their quotes—it’s usually clear how pricing changes with quantity. If a company goes through 30,000 washers a month, those bulk savings can add up to hundreds per order, making a real difference over a year.

These savings provide companies with more flexible purchasing options – without being constrained by budgetary pressures, they can prioritize high-quality self-locking washers and avoid cheaper options that may be less stable despite their price.

Product details

Dual acting double ended self locking washers aren’t really made in bright or fancy colors—most of their coatings are for practical reasons, not for looks. You’ll typically find these washers have a minimalist finish, with three main styles common: pure silver, often made of steel or stainless steel; a light grey, achieved through a galvanizing process, which also offers rust resistance; and a deep black oxide coating, which not only prevents rust but is also visually more discreet.

Sometimes they come in yellow zinc, which protects even better against rust—useful outdoors or in damp places. But you won’t find bright or colored versions since these parts go inside machines where looks don’t matter—it’s all about function.

The finish helps fight corrosion, makes them easier to install, or keeps them from sticking. For example, zinc-plated ones might be used outside, while black oxide versions often go inside equipment where they’re out of sight.

Custom colors are pretty unusual, though some suppliers might do them for very large orders—like if a company wants to color-code parts during assembly.

Product Materials

Bual acting double ended self locking washers are typically made of carbon steel, stainless steel (including SS304/SS316), and alloy steel to meet the mechanical performance requirements of various scenarios. We offer zinc plating, yellow zinc plating, and general corrosion-resistant surface treatment options, allowing for customized solutions tailored to your specific operating environment (such as humidity, corrosive media, and temperature).
