Heavy duty external tooth lock washers.
410 stainless steel for strength and durability.
External tooth lock washers create a ratchet action by biting into the nut or screw head and the surface it contacts.
When used under a screw or bolt head, external tooth washers require a large head, such as a pan or round head, so that the washer teeth can make contact with the head.
Since the teeth are on the largest radius, which results in greater twisting resistance, this type of washer is preferred when the greatest locking power is desired.
Available in several sizes.
Please choose the washer you need from the drop down menu above the product description.

Combine this purchase with other items in our store for discounted shipping.
Most marine hardware can be divided into two distinct groups these days.
Cheap junk made with little, if any, thought to the impact its production has on the environment or the workers involved - or high quality gear made from materials designed to last, by companies that care.
We prefer to carry the latter.
Plastic and nylon parts are durable for a while and they satisfy price sensitive shoppers. Their production, however, creates numerous toxins, and eventually enough sunshine or stress will cause them to break.
Chrome, nickel, and zinc plating can protect metal surfaces for years, but their initial production, especially in third-world countries can cause devastating harm.
Painted parts are effective for a while, but paint production is usually nasty, and as it chips and goes over the side, paint carries its own poisons along.
At GreenBoatStuff we choose to carry aluminum, brass, bronze, stainless steel, and occasionally wood hardware.
In an imperfect world we know these choices are not entirely without their faults.
In our opinion, however, they satisfy our criteria for high quality, long lasting products that do the job well while inflicting minimal, if any, harm.
Another important green aspect to our hardware offerings is our lack of a minimum order policy.
Unlike most hardware suppliers that force you to purchase in bulk, at greenboatstuff we try to avoid such restrictive policies.
After all, if a customer only needs a certain quantity of an item, why force them to pay for something that will sit on a shelf for years or be discarded?
Sure, this might sound like a little thing, but if we can discourage waste, especially of products like hardware that are made almost exclusively from natural resources, we believe it is both good business and good for the Planet.
