Marine Fasteners Flat Washers

Marine Fasteners Flat Washers are stainless steel flat washers (also called plain washers) for boat, marine and other moisture-prone fastening jobs. Each washer is a thin, disc-shaped plate with a center hole. It sits under a bolt head or nut to spread the clamping load over a wider area.

Key Features:

• Stainless steel construction resists rust and corrosion in wet, humid and saltwater-exposed locations
• Load distribution helps prevent the fastener from pulling into or marring the mounting surface
• Smooth, flat bearing surface gives a consistent seat for bolts, machine screws and nuts
• Wide range of sizes available to match different fasteners
• Versatile use on hardware, fittings, cleats, trim and general marine projects

Pair these flat washers with matching stainless fasteners to keep hardware consistent and avoid mixing metals. They are a dependable, low-cost way to protect surfaces and keep joints secure on boats, docks and other outdoor equipment.
