Great connector as always!
The most important thing, they do what they were designed to do! I use a lot of engineered fasteners and they are well worth the cost. In a time where so many construction materials are pushed to their limit of lowest cost/weight/install time, these have made my life easier many times.

Powerful Fasteners
These screws go through wood like butter with no pre-drilling and they have great holding power. Great product.

Very good, used them to secure two fourteen foot 2x8's together. I used only a few in each beam because of the cost of these, then I used other structural screws every few inches. Simpson is a trusted name, and these screws are perfect..
