What Size Torx Bit for Trex Hidden Fastener?

Choosing the Right Tool to Make Your Project a Success

When it comes to installing decking, Trex hidden fasteners are a popular choice for many homeowners. They offer a clean, seamless finish with no unsightly screws or nails to detract from the look of your deck. However, using hidden fasteners can be a bit tricky, especially if you're new to decking installation. One of the most commonly asked questions when it comes to Trex hidden fasteners is, "What size Torx bit do I need?" Here's what you need to know.

Understanding Trex Hidden Fasteners

Before we dive into the specifics of Torx bits, let's take a moment to talk about the Trex hidden fastener system itself. Trex offers two types of hidden fasteners: the Universal Fastener and the Hideaway Hidden Fastener. Both systems work by attaching the deck boards to the joists from the side, rather than from the top, which is something you would do if you were using screws or nails.

The Universal Fastener is a plastic clip that installs between the edge of the board and the joist, and it's designed to work with any kind of decking material, including composite and wood. The Hideaway Hidden Fastener, on the other hand, is exclusively designed for Trex decking, and it features a stainless steel clip that installs between the grooved edge of the board and the joist. In either case, the installation process is largely the same.

The Role of Torx Bits

To install Trex hidden fasteners, you'll need a special tool called a Torx bit. Torx is a type of screw head that has a six-pointed star shape, and it's designed to be used with Torx screws, which are commonly used in machinery, electronics, and, in this case, decking installation. The purpose of the Torx bit is to fit snugly into the fastener's screw head, giving you the grip you need to tighten the screw in place.

Choosing the Right Size

Now that you know what a Torx bit is and why it's important, it's time to determine what size you need for your Trex hidden fastener installation. The size of the Torx bit you need will depend on the type of fastener you're using. Here's a quick guide to help you choose the right size:

For Trex Universal Fasteners: You'll need a T20 Torx bit to install Trex Universal Fasteners. This is the same size that's used for many standard deck screws, so you may already have one in your toolkit.

For Trex Hideaway Hidden Fasteners: You'll need a T20 Torx bit if you're using Trex Hideaway Hidden Fasteners with grooved deck boards, and a T15 Torx bit if you're using the system with non-grooved deck boards.

Overall, the most common size you'll encounter when installing Trex hidden fasteners is T20, so having this size on hand is a good idea. Additionally, some Torx bits are designed to fit multiple sizes of fasteners, so it's worth investing in a set of bits that will give you versatility when you're working on various projects.

Tips for Successful Installation

Now that you know which size Torx bit you need for your Trex hidden fastener installation, here are a few tips to help you get the job done right:

- Use a bit that's in good condition. Torx bits can wear out over time, so make sure you're using a bit that's in good shape and isn't stripped or damaged.

- Apply even pressure. When you're driving the screws into the fasteners, make sure you're applying even pressure to the Torx bit. This will ensure that the screw is properly seated and won't come loose over time.

- Check your work. Once you've installed all of your fasteners, take a moment to double-check your work. Make sure each fastener is tight and properly seated, and that the boards are secure.

With the right Torx bit and a little patience, you can achieve a professional-looking finish on your Trex decking project. Whether you're tackling the installation on your own or hiring a professional, knowing what size bit to use is the first step toward success.
