10×1-5/8 Reamer Tek Torx Head Screws
These self-drilling screws are designed to fasten wood to mild steel or aluminum, with a maximum wood depth around 7/8″ and a bore capability up to 1/8″ in metal. They use a Torx/Star drive (T-25) for higher torque with less cam-out, though the drive bit is not included. The overall length is 1-5/8″ and the shank diameter is ~0.19″.
14×2-3/4 Reamer Tek Torx Screw
Specifically intended for wood-to-metal applications, these screws caution that the listed screw length does not represent usable thread length. They are designed for mild steel or aluminum and require caution around welded or tempered metal. They are not advised for very thick metals but offer strong holding power for trailer and deck installations.
#10 x 1-5/8″ Reamer Tek Torx
These Tek screws are designed for softwood and hardwood, with deep, wide threads for high holding power without pre-drilling in many cases. They’re heat-treated and coated with bronze star ceramic for exterior protection, and are ACQ lumber compatible. The threads are engineered to drill into wood and self-tap into steel or aluminum.
#10-16 x 1-1/4″ Wood-To-Metal Screws
Bronze-coated wafers designed for exterior use, these self-drilling screws are engineered for wood-to-steel or wood-to-aluminum fastening, delivering higher torque with the Torx/Star drive to reduce slippage compared to Phillips. They’re ACQ lumber compatible and suitable for various outdoor projects.
14×3-1/4 Reamer Tek Torx Screws
Large, heavy-duty Tek screws designed for trailer decks and similar applications, with a maximum wood depth near 1-15/16″ and a metal bore capability up to 1/4″. They use a T-30 Torx head and measure 3-1/4″ in total length with a shank diameter of ~0.24″. The instruction graphic should be consulted to interpret usable thread length.
Buying Guide
Key considerations when selecting wood-to-aluminum screws:
- Material compatibility: Look for products labeled for wood-to- aluminum and mild steel use to ensure proper bonding and corrosion resistance.
- Drive type: Torx/Star drives provide higher torque transfer and reduced cam-out, especially in harder woods or thicker metals.
- Thread design and length: Reamer Tek screws feature aggressive threading for faster drilling and secure gripping. Be mindful that stated screw length often does not equal usable thread length.
- Corrosion resistance: For outdoor or trailer use, choose screws with bronze or ceramic coatings and stainless steel variants where appropriate.
- Wood depth vs. metal thickness: Consider the maximum wood depth and metal bore capacity to avoid stripping or incomplete seating.
- Pre-drilling needs: Some self-drilling screws are designed to reduce drilling resistance, but pre-drilling may still be necessary for thicker or harder materials.
- Environment and lumber type: If using ACQ-treated lumber, ensure compatibility to prevent corrosion and ensure a long service life.
- Coatings and finishes: Exterior-use screws with protective coatings help prevent rust in humid or salt-exposure areas.
- Performance in trailers and decks: Screws listed here show good results for trailer decking, flatbeds, and other wood-to-metal assemblies where aluminum or mild steel is involved.
- Quality controls: Look for packs with consistent thread depth, sharp cutting edges, and reliable coatings to ensure predictable performance across multiple fasteners.
