What Customers Are Saying

Customers overwhelmingly praise these mending plates for their strength and reliability in joining wood pieces securely, with most reporting they hold better than nails and perform exactly as needed for structural reinforcement. Many appreciate the sharp prongs that allow easy hammering into standard lumber like 2x4s and 2x6s. Several note difficulty driving them into dense or pressure-treated wood, requiring a heavy hammer and solid surface. A few mention minor quality concerns, but overall, reviewers consider them highly effective and dependable for reinforcing wood joints.

Difficult to secure

Would Not Recommend

Was purchased to splice butt joints on a deck roof. They would not stay in. Get one side in, start hammering the other, and the first side would pop back out

Cool

Would Recommend

This is pretty cool and the pins are super sharp. I definitely used it wrong though and bent them all in different directions. Looking forward to learning how to actually use them since they seem helpful and are pretty cheap

Use them to help the drafters

About all at Lowe’s had where I’m building our gazebo that has put the rafters together. Makes it easier to build.
