Material quality dictates whether your fasteners hold firm or strip out under pressure. I compared these three options by analyzing buyer feedback so you do not have to guess. In my view, matching your hardware to the scale of the job prevents costly mistakes. Let us see which option earns a spot on your workbench.

1. 100 Pcs 1.77 Inch Plastic Washers – 45mm Polypropylene Foam Board Fasteners, Insulation Washers for Fixing and Fastening Rigid Foam and Load Spreading
These polypropylene washers earned their ranking through generous load spreading capabilities. The wider 1.77 inch surface area prevents your screws from crushing fragile rigid foam.
I think this plastic design works well for weekend projects where metal fasteners might cause thermal bridging. You do need to mind the polypropylene material if you are working in high heat environments.
Buyers note that the large diameter distributes pressure evenly across soft insulation boards.
Reviewers appreciate the non-corrosive plastic construction for damp spaces.
Some users wish the pack size was larger for multi-room renovations.

3. QWORK Foam Board Fasteners Washers, 300 PCS 1-1/8" Steel Washers for Fixing Insulation Board Foam Board
A modest 300 count count provides a clever middle ground for medium remodeling tasks. These steel plates feature a precision-engineered diameter that balances holding power with ease of placement.
I like this kit for garage updates or basement finishing where the larger pack is overkill. You still get the durability of solid steel without buying surplus hardware you do not need.
Buyers find the mid-tier quantity ideal for single-room insulating projects.
Reviewers highlight the sturdy metal build that prevents pull-through.
Some feedback notes the lack of included fasteners in the box.

Choosing Between Them
Choosing the right hardware depends entirely on your project scope, so I recommend the QWORK 500 PCS steel washers for heavy-duty commercial jobs because the massive bulk quantity saves you time and money. If you are tackling smaller weekend projects, the 1.77 inch plastic washers suit DIY home projects far better, while the 300 count steel set fits medium remodeling tasks.
Keep in mind that none of these options include screws in the package. You will need to source your own fasteners separately to match the specific depth of your wall assembly.
