Did as needed...
Worked well. Just be aware that depending upon what the tines are sinking into, simply tightening the carriage bolt might not be enough to make them sink in. You may need to use a hammer and punch to set them first

Right on the Money
In Construction sizes are a bit daunting. I measured the square part of my Closet Bolt, it was 5/16, I ordered 5/16 size and fit perfect. Fixed my plastic wheel barrow. I'd recommend using these BEFORE the Wheel Barrow cracks, cause they all do.

work Great with soft wood.
Used it for both soft and hardwood. Had to hammer it flat Before tightening the bolt with hardwood; But, I used it for the design effect. works great with pinelumber and looks good too.I was very saticfied with this product.

They work.
Out of 4 smaller hardware stores and the 2 giant ones no one had any. Received them faster than expected which was GREAT!

Good product
These washers are easy to use. The teeth grasp the wood and prevent rotation while securing the nut. I spray painted these, along with the lags, black for a more finished look to the deck.

Tangs just fold over, do not drive into wood
Tangs are too thin to begin with, they do not drive into the wood. They just fold over.

Fits the collar perfectly
Excellent for use with 5/16th carriage bolts in wood. About the size of a quarter.

Works perfect with carriage bolts and couldn’t find anywhere else
Glad these were as described and worked well with the carriage bolts from Home Depot. The square under the head of the carriage bolt locks perfectly into place and these prevent the head from digging into the wood.

As expected, fast shipping

Not the right size. Does not fit a 3/8 bolt.
Would need to be larger then .375. I have tried 5 washers and they are all the same size and do not fit the bolts.

First time usage.
Can't comment at this time, but it looks like a good product.

These are awesome for any deck work
Thees are legit and a good product. Not sure why no local retailer sells them. They are a great piece of material to use when just need your build to be solid and keep from tearing out your wood..
