1.5 Inch Perforated Insulation Pins Self Locking Washers Flat Washer Round Galvanized Steel Plaster Washers for Wall and Ceiling (200 Pieces)

Reasonable price. Good quality. On time. And they work on duct liner stick pins

Just what I needed!

As advertised and less$ than most

Promt arrival. Good quality

A good little product But the slits next to the opening allow screws to be pulled through need to use a fastener with a large head

These washers are great! Mind literally blown on how useful these are. One of my taillight assemblies had deteriorated around the holes where the screws go that hold it in place. This created an oversized hole for the screw. I didn't want to have to buy another assembly just because of this particular issue. Another issue was that the performed holes in the assembly were recessed. I found these washers and they did the trick. Saved me a lot of money 💰. They are flexible and came at a great value. I got a lot of washers in the box that I purchased for a decent price! I'm very satisfied with this product! 👍👍👍👍👍

I believe these are designed for holding insulation in place. I used them to secure my old failing plaster walls and ceiling's before mudding them over and painting. Good price!

I used this Item in a insulation application, this has durability and security for this fastener, I was able to secure corragated sheetmetal for my project.
