High-Performance Construction Wood Screw with Deep Coarse Thread for Timber Framing

Deep Coarse Thread:

• Specifically designed to bite into the fibers of structural timber, providing superior load-bearing capacity and vibration resistance.

Shank Scraper/Reamer:

• A specialized section on the shank clears the hole in the top piece of timber, preventing "jacking" and ensuring the two pieces are pulled tightly together.

Reinforced Head Design:

• Extra-thick countersunk head to prevent head-shearing when driving into dense hardwoods or large structural glulam beams.

Advanced Wax Coating:

• Every screw is treated with a friction-reducing wax that facilitates smoother entry and protects the zinc coating during high-torque installation.

Torx/Star Drive:

• Available with a high-performance Torx drive system for maximum power transfer and zero cam-out, essential for long-length structural screws.

Medium Carbon Steel:

• Heat-treated for high shear strength, crucial for structural connections.

Yellow Zinc Plating:

• Provides a professional finish and essential protection against humidity.

Mechanical Galvanizing:

• Recommended for treated timber (ACQ) to prevent chemical corrosion.

Anti-Friction Wax:

• Applied post-plating to ensure consistent installation performance.

Timber Frame Construction:

1. Joining wall studs, floor joists, and roof rafters.

Log Home Assembly:

2. Securing large logs and heavy timber beams.

Decking & Boardwalks:

3. Heavy-duty fastening of sub-frames and structural supports.

Roofing:

4. Attaching purlins and battens to main structural members.

Landscaping:

5. Constructing retaining walls, pergolas, and heavy-duty garden structures.

Bridge Construction:

6. Small to medium scale timber bridges and pedestrian walkways.

Q: Why use a Torx drive for construction screws?

1. A: Construction screws are often very long and require high torque. Torx drives offer a larger contact surface, preventing the bit from slipping and damaging the screw or the workpiece.

Q: Are these screws suitable for use with pressure-treated wood?

2. A: For modern pressure-treated timber (ACQ/CA-B), we recommend our mechanically galvanized or stainless steel screws to prevent premature corrosion.

Q: Do I need to pre-drill for these large screws?

3. A: Our screws feature a Type 17 point and wax coating which usually eliminates the need for pre-drilling, even in dense timber. However, pre-drilling is always safer near the ends of boards.

Q: Can these screws replace traditional coach bolts?

4. A: Yes, our large-diameter construction screws (8mm+) are often used as high-efficiency alternatives to coach bolts (lag screws) in many structural applications.

Q: What certifications do you provide?

5. A: We provide Mill Test Reports (MTR) and certificates of conformity. We also accept inspections by SGS, BV, and TÜV.
