Washers
Washers provide a greater bearing surface under the fastener. This helps prevent a nut, bolt or screw from pulling through the material.

| Flat washers |
Used under the head of a bolt or nut to distribute the forces applied when tightening.
|
An alloy of copper with good corrosion resistance. Once common for marine use, brass is now used mostly in decorative applications.
|
|
Stainless steel 18-8 is an alloy of steel with high corrosion resistance. Stainless has become the material of choice for exterior and most marine applications.
|
|
Bronze is an alloy of copper with greater strength and corrosion resistance than brass. Most commonly used in wood boat building and restoration.
|
|
| USS flat washers |
Used under the head of a bolt or nut to distribute the forces applied when tightening. USS pattern is the most common type of flat washer.
|
Steel is zinc plated for moderate protection against rust.
|
|
Made from tempered medium carbon alloy steel and zinc plated. Best for applications where high strength and hardness is required.
|
|
Hot dipped galvanized fasteners are much more corrosion resistant than zinc plated fasteners. Due to the thickness of the galvanized coating, galvanized bolts will only work with galvanized nuts. For exterior and coastal area use. (ASTM A153)
|
 A grade 2 fastener with a bright mirror-like finish providing sharp looks for a variety of applications.
|
|
| SAE flat washers |
Used under the head of a bolt or nut to distribute the forces applied when tightening. SAE pattern is a tighter fit on the bolt and a smaller outside diameter.
|
Steel is zinc plated for moderate protection against rust.
|
|
Made from tempered medium carbon alloy steel and zinc plated. Best for applications where high strength and hardness is required.
|
A grade 2 fastener with a bright mirror-like finish providing sharp looks for a variety of applications.
|
|
| Fender washers |
Used under the head of a bolt or nut to distribute the forces applied when tightening. Fender washers have a large outside diameter.
|
Steel is zinc plated for moderate protection against rust.

Stainless steel 18-8 is an alloy of steel with high corrosion resistance. Stainless has become the material of choice for exterior and most marine applications.
|
A grade 2 fastener with a bright mirror-like finish providing sharp looks for a variety of applications.
|
|
| Lock washers |
Lock washers place tension against a nut after tightening, to help prevent the nut from loosening.
|

|
|
| Lock washers external tooth |
Uses external teeth for locking and tension.
|
Steel is zinc plated for moderate protection against rust.
|
|
A stainless alloy harder than the 18-8, but not as resistant to corrosion as 18-8.
|
|
| Lock washers internal tooth |
Uses internal teeth for locking and tension. Less aggressive than external tooth with a smaller outside diameter.
|
Steel is zinc plated for moderate protection against rust.
|
|
A stainless alloy harder than the 18-8, but not as resistant to corrosion as 18-8.
|
A grade 8 fastener with a bright mirror-like finish providing sharp looks for a variety of applications.
|
|
| Finishing washers |
Made for flat or oval head screws for a finished look.
|
An alloy of copper with good corrosion resistance. Once common for marine use, brass is now used mostly in decorative applications.
|
|
Steel that is nickel plated for appearance.
|
|
Stainless steel 18-8 is an alloy of steel with high corrosion resistance. Stainless has become the material of choice for exterior and most marine applications.

Bronze is an alloy of copper with greater strength and corrosion resistance than brass. Most commonly used in wood boat building and restoration.
|
|
| Dock washers |
Used to distribute the forces applied when tightening. Dock washers have a larger outside diameter than standard and are thicker than standard.
|
Hot dipped galvanized washers are much more corrosion resistant than zinc plated washers. For exterior and coastal area use. (ASTM A153)
|
|
| Square dock washers |
Used to distribute the forces applied when tightening. Square dock washers have a large square outside and are thicker than standard washers.
|
Hot dipped galvanized washers are much more corrosion resistant than zinc plated washers. For exterior and coastal area use. (ASTM A153)
|
|
| Ogee washers |
Ogee washers are thick, large diameter, cast iron washers. They have a curved or sculpted appearance and are typically used in dock and wood construction to prevent bolt heads and nuts from pulling into the wood.
|
