## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by K***N on October 3, 2022*

This is a great product and one of my favorites and the price was awesome

### ⭐⭐⭐⭐⭐ Much cheaper than anywhere else!
*by M***E on May 8, 2013*

These screws are real expensive, yes. However, they are the best code-tested structural screws for multiple LVL beams. No glue was called for if I used these screws (I put some construction adhesive in anyhow). Follow the fastener schedule that the manuf of the beam(s) call for and you can't go wrong!

### ⭐⭐⭐⭐⭐ Five Stars
*by U***S on August 1, 2017*

Did a great job binding two thicknesses of microlam beam together for my 20' garage door header.
