Overview

Hidden Fastening Made for PVC Trim

Get a clean, seamless finish on PVC trim and decking projects with PVC Cortex Screws. Designed specifically for use with the Cortex Hidden Fastening System, these screws secure boards firmly while allowing you to conceal fastener heads with matching plugs. As a result, your finished project looks smooth and professional.

Engineered for PVC Applications

PVC trim expands and contracts with temperature changes. These screws account for that movement and provide strong holding power without causing surface damage. Because of this, they help maintain a secure fit and long-term durability.

Clean, Professional Results

After driving the screw, simply insert the matching PVC plug to cover the fastener head. This creates a virtually invisible finish that blends with the board surface. In addition, the system helps prevent surface cracking and mushrooming during installation.

Built for Exterior Performance

Outdoor projects demand reliable materials. These Cortex screws resist corrosion and hold strong in exterior conditions, making them ideal for fascia, trim, decking, and other PVC applications.

Convenient Box for Efficient Installs

Each box includes screws designed to work seamlessly with the PVC Cortex system, helping contractors and DIY builders complete projects efficiently and with fewer interruptions.

Had a great experience with the sales rep. He was very knowledgeable and honest. We ended up buying some thermally modified ayous panels for an outdoor media wall. So far so good. It looks great and hopefully will last for decades… Thank you!! Everyone has told us how much they really like the cladding used for our media wall and we appreciate your help with our project.

Best prices and quality I found after looking at a few different places for lumber for my deck project. Customer service was excellent and they helped me with my selections, staff was very knowledgeable! Highly recommend Beyond Lumber and they will be my go to place for future projects.

Roy and his team are hard to beat. These guys are great, I’m a deck builder myself and their customer services is on point. Thanks for all your help team!

We had an excellent experience with Beyond Lumber. Their team was knowledgeable, professional, and guided us through every step of choosing the right materials. The quality of the IPE and other hardwoods was outstanding—everything arrived on time and exactly as promised. Beyond Lumber truly cares about customer service and delivers top-notch products. Highly recommend them for anyone looking for premium decking and outdoor materials

I started buying IPE from Brazilian Lumber over one year ago before the vendor opened the California location (i.e. where I am located). There were some issues related to the lumber (IPE), BUT the vendor made sure that all was taken care of and that I was happy. I mentioned “the issues” not to say that they product is bad, but rather to stressed out that the vendor provides superb service. No matter what you do, the problems may happen. Important is how such situations are handled. I was working with Luis, great guy to work with. I recommend this vendor.

I upgraded my backyard with Ipe deck tiles for my patio. It was definitely an investment, but it’s turned out to be worth every penny. The tiles were easy to install and the finished product is not only beautiful, but also incredibly durable and functional. I would highly recommend Ipe deck tiles to anyone looking to create a beautiful and long-lasting outdoor space.
