Heavy Jam Nut > Silicon Bronze > 1/2", 5/8", or 1" Sizes.

When only the best will do, use our marine grade silicon bronze heavy jam nuts.

Product Features:

Heavy hex jam nuts are thinner than a standard hex nut but have the same dimension across the flats and corners.

Hex jam nuts have two common applications.

A jam nut can be threaded onto a bolt and run tight against the standard nut which will lock the nut in place and prevent it from backing off.

Jam nuts are sometimes used for leveling purposes as well.

Our high quality marine grade Silicon Bronze fasteners contain about 3% Silicon, for maximum corrosion resistance and superior durability.

Bronze is a favored material to use for traditional boat fittings because it takes casting, machining, and polishing very well, is relatively strong and incredibly resistant to salt water.

While bronze is often more expensive initially than other marine grade materials, this expense is easily recovered through the high strength and long life bronze provides.
Sold individually.

Available in three sizes.

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 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.
