Top quality beats a cheaper price
Have used these for years and they are wonderful. Tried one of the generic products and was disappointed in the quality ( returned for a refund) so I went back to these. Will not be tempted to sacrifice quality for the price again!

Fantastic Product!
These are great for metal connector installs on pressure treated lumber and my 1/4 Dewalt impact drives them in with ease. They are the best choice for the application mentioned.

Solid screw, great price
This isn’t always the case but, this time they sent five 100qty packs, instead of one 500 pack, which is totally fine with me. I do like using screws instead of the nails just in case I have to take it apart… it’s super hard to disassemble hangers when they are nailed. I’ve used these for most of my Simpson strong tie hanger installations. I generally use these shorter ones when screwing horizontally into the two by to secure the joist hanger. Then use the longer ones like the 2 1/2 for when I’m screwing into something thicker.

Quality Product
Went through hundreds of these when building my deck. Don't skimp on quality. Buy these for all your hangers and clips etc.
