Grip Rite GC1 1-Inch Round Plastic Cap, 2,000 Count

Round Plastic Cap Nails are great for holding underlayment in place, that may be left exposed for a while. I recommend getting a hammer with a magnet in the face for installing them. With a little practice you can drive them with one blow and move very fast.

They are very easy to hammer and conveniently easy to see

Easy to use, a necessity for securing Tyvek underlayment. Shallow wide head covers a good swath of material to hold it in place, the low profile prevents raised impressions from walking on the roof and allows positive snaplock action to secure one panel to the next. Less than a 5% drop out from manufacturing errors (off center nail, double plastic caps on a single nail). Ring shank nails prevent backing out of the plywood sheathing.

Live in western iowa where it is always windy have had a playhouse for the kids wrapped since june with no issues with letting go or tearing of wrap

1" nail, will not work on masonry.

I'm glad I checked buyer comments on the tyvek posted/no trespassing signs I bought. These nails really are a better solution than using an arrow staple gun. For some of the old growth trees on my property, the bark is very thick with deep grooves. These nails with the plastic washers would be the only way the signs would stay put on most of the trees. Next time, I may order a few of the 1.5" washer nails as well. The staples would have just fallen out if I used them. Thanks guys, Amazon buyers included, for directing me to the correct product for my application.

Very prompt service. Product exactly as described and easy to use.

Nails bend easily but to in easy ounce you get used to pounding them
