Shipping Details

Deck Plus flat washers are great for adding resistance to your bolts and screws to prevent them from boring into the wood and weakening it. These Deck Plus metric epoxy coated flat washers are finished with a tan-colored duplex coating and designed to fit bolts, screws and nuts of similar size & finish. When selecting a washer, be sure to pick one that matches the fasteners you are already using. Picking a different finish may cause a chemical reaction, weakening your fasteners over time.

Ideal for deck building and exterior wood projects
Black epoxy coating offers superior resistance to rust and corrosion
Meets most local building code requirements required by municipalities nationally
Will not bleed or stain cedar or redwood
Recommended for treated lumber
Parts carry a limited lifetime warranty against rust and corrosion

What Customers Are Saying

Customers overwhelmingly praise these washers for exceptional durability, perfect fit, and aesthetic appeal. The thick black epoxy coating resists chipping and scratching even under impact driver torque, while precise sizing eliminates adjustment needs for deck and pergola projects. Many highlight the sleek finish that complements modern outdoor structures and matches existing hardware. The ceramic-like appearance and professional look consistently satisfy users. A few note slight slipperiness during handling, though this causes no functional issues. Overall, reviewers strongly recommend them for outdoor fastening applications.

Solid Quality Hex Nuts for Easy Install

Would Recommend

These washers were well made with consistent quality throughout the box. They installed easily into my treehouse project and worked smoothly without issues. The design made them simple to tighten securely with a socket each time. I’d definitely use them again

Its a flat washer.

The hardest part about using this was deciding which flat side goes towards the nut.

Works well

Would Recommend

We needed lag bolts and washers to hang a fairly heavy squirrel house. These did the trick and seem to be heavy duty.
