Washers are a key component in boatbuilding, generally used around a bolt or a screw to form a seat for the head or nut. We offer a wide variety of fasteners in different sizes and metals for your every boatbuilding need.

Flat Washers: The most common type of washer, used to distribute the force/stress of a nut or bolt. They can also help reduce friction and heat when turning a bolt or nut. Basic flat style washers are available in two types of Stainless Steel, Brass, Galvanized, and Silicon Bronze.

Dock Washers are also used to distribute tightening force, but are larger in terms of their outside diameter, and thicker than normal. Available in galvanized.

Fender Washers also feature a larger outer diamter, and are used for distributing force/stress as well. They are available in stainless steel and 316 stainless.

Lock Washers prevent a nut from loosening by placing tension on it. Notice that lock washers are actually split and slightly coiled. This is what gives them their locking characteristics. Available in inch based and metric sizes (s/s only), in galvanized, 316 ss, stainless steel, and silicon bronze.

Finish or Finishing Washers are used mostly for decorative purposes to give projects a 'finished' look. Available in brass or stainless steel, they work best with oval or flat head screws.

Pryamid Washers are zinc-plated, star- shaped, and perfect for use with U-bolts in heavy duty applications.

External Tooth Washers are a locking type as well, utilizing extneral teeth (looks almost like a gear) for tension. Available in stainless steel.

Internal Tooth Washers also feature locking 'teeth', but have generally smaller outer diameters than the external type. Available in stainless steel.
