The classic wood post solution, upgraded. Featuring distinct Left & Right Handed lag screws in our premium Black Titanium PVD finish. A robust, rustic-industrial look that stands the test of time.

Overview

Designed specifically for wood posts, the RiaYer Black Titanium Swage Lag Screw System offers a straightforward, secure way to build your deck or stair cable railing. By pairing a Left-Hand Thread screw with a Right-Hand Thread screw, you can tension the cable simply by rotating the wire itself, completely eliminating the need for bulky, unsightly turnbuckles.

Why Choose This Kit?

  • 💎 Black Titanium PVD Finish: Experience the gold standard in coating. Our Vacuum Titanium Plating ensures the black finish is bonded to the molecular structure of the steel. It creates a metallic, scratch-resistant surface that won't peel, flake, or chip like standard paint.
  • 🔄 Left & Right Hand Tensioning: The kit includes paired screws (one left-thread, one right-thread). This smart design allows you to tighten the cable span simply by rotating the wire rope—no extra tensioners needed.
  • 🌲 Built for Wood Posts: The deep-biting lag screw design anchors firmly into timber, providing a massive 1,200+ lbs (580 kg) of pull-out strength for maximum safety and code compliance.
  • 🔧 Upgraded Installation Tool: We include a custom-molded wrench designed specifically for these screws, preventing surface scratches during installation (a common issue when using standard wrenches).

How to Install:

  1. Mark & Drill: Mark holes on your wood posts. Use the included drill bit to create pilot holes (essential to prevent wood splitting).
  2. Crimp: Swage the Left-Hand screw to one end of the cable and the Right-Hand screw to the other end using a hydraulic crimper.
  3. Install: Screw both ends halfway into the posts.
  4. Tension: Rotate the entire wire rope. The opposing threads will draw the screws into the posts simultaneously, tightening the cable.
  5. Lock: Once taut, secure the screws firmly with the included specialized wrench.

FAQ:

Q: Why do I need Left and Right hand threads?
A: This creates a turnbuckle effect without the actual turnbuckle. When you rotate the wire, both screws pull inward simultaneously, tensioning the line while keeping the look clean and simple.

Q: Will the wrench scratch the black finish?
A: Standard metal wrenches might. That’s why we include a custom-designed wrench in the kit, specifically shaped to minimize contact damage and protect the PVD Titanium coating.

Q: Can I use this on metal posts?
A: No. Lag screws are designed with coarse threads to bite securely into wood. For metal posts, please check our "Invisible Receiver" series or "Toggle Bolt" kits.
