I recently purchased these collated fasteners for a construction project and was impressed with their quality. Through trial and error, I found that they seamlessly fit into my tool and had superior holding power. Additionally the packaging was durable and made for easy storage on the site. Its industrial and scientific design made this purchase a no-brainer for any project needing TOP-NOTCH fasteners. The only downside is the cost, but the extra expense is well worth the reliability these fasteners provide..
