Wafer head Tek screws fasten wood to light gauge steel framing. The wafer head large flat surface distributes load and resists pullout through the wood material, while the Tek tip self-drills into the steel without pre-drilling.

A wafer head is wider and flatter than a pan head, giving more bearing surface for better pullout resistance in wood. Pan heads are more compact and better for metal-to-metal connections. For wood-to-metal, wafer head is the preferred choice.

The #10-16 wafer head Tek screw is designed for light gauge steel from 18 gauge to 12 gauge (0.0478 to 0.1046 inch thick). For heavier steel, a larger Tek drill point number is required.

Most #10 wafer head Tek screws use a T-20 or T-25 Torx bit. Check the specific product listing for the exact drive size required for your screw diameter.

Wafer head Tek screws are primarily for wood-to-light-gauge-metal wall and floor connections. For metal roofing applications, use hex washer head roofing screws with EPDM washers designed for weatherproof fastening.

The self-drilling tip reduces split risk compared to standard wood screws, but in thin or dry wood, driving near the edge can still cause splitting. Position screws at least 3/4 inch from board edges and use the smallest effective screw size.

Yes. Wafer head Tek screws can be removed with the appropriate Torx bit in a power drill set to reverse. Removal may enlarge the hole in the thin steel, reducing grip if the same hole is reused.

Wafer head Tek screws use a coarse thread on the shank section that grips the wood, and no thread on the drill point section. The thread specification is included in the screw designation (such as #10-16 meaning 16 threads per inch).

Yes. Wafer head Tek screws are commonly used to attach OSB, plywood, or dimensional lumber to light gauge metal stud framing in commercial and manufactured home construction.

A standard cordless drill with the correct Torx bit drives wafer head Tek screws effectively. An impact driver can also be used but may over-drive the screw into the wood layer. Use torque control when available.
