Frequently Asked Questions (FAQ):

Q: Are these washers compatible with metric bolts?
A: No. They are USS washers sized for 3/8-inch inch-based coarse-thread fasteners.


Q: Can they be used outdoors?
A: The zinc plating offers basic corrosion resistance; for harsh outdoor or marine environments, consider stainless steel washers.


Q: What type of bolts should I pair with these washers?
A: Use 3/8-inch coarse-thread (USS) bolts or screws with matching zinc finish to avoid galvanic corrosion.


Q: Do these washers prevent wood damage?

Attractive and strong shelves.
Color: Dark Carbonized Pine, Size: 16.5 x 6.1 x 0.59 inches
These shelves are not only easy to install, but they look great too. I made a Mimi bar and these were strong enough to hold My liqueurs as well as glasses.

This was everything I needed. And it was exactly as described. And I really like the multiple ways that the brackets can be used. Good product. And a very good price.

Read the sizes
Color: Black, Size: 16.5 x 6.1 x 0.59 inches
These look bigger and wider in the photos, but they are small, so read the measurements before buying. They are not real wood but they are sturdy and look great on my wall! They are easy to put together also. I love them!

Such a good price!
Color: Dark Carbonized Pine, Size: 16.5 x 6.1 x 0.59 inches
Love them! They are so cute, couple notes. The wood doesn’t come with pre drilled pilot holes for attaching the brackets so you will need a drill/drillbits. It is real wood which impressed me, but outside tools definitely required. Including a level!! The “level” they offer is indeed a bubble in liquid, but it’s about an inch long, 1/2in wide and a cylinder so probably the most useless, cutest level I’ve seen in my life. Otherwise great! They hold exactly what I need.
