S-94053A130 1/4"-20 x 3" Wood Screws

Key Features & Benefits at a Glance

• Effortless Self-Drilling Installation: Integrated cutting wings and a No. 4 drill point eliminate the need for pre-drilling, saving significant time and labor in assembly.
• Superior Corrosion Resistance: The specialized corrosion-resistant coating on the steel body ensures long-term durability and reliability in various environments, reducing maintenance costs.
• Robust Fastening in Multiple Materials: Engineered to penetrate and form strong threads in both sheet metal (0.13"-0.25") and wood (0.75"-2"), offering exceptional versatility.
• High-Torque Driving & Secure Fit: The Phillips No. 3 drive provides a positive grip for high-torque application, while the standard flat head sits flush for a clean, professional finish.
• Optimized Thread Design for Maximum Grip: Fully threaded with UNC coarse spacing ensures rapid installation and superior pull-out resistance in wood and metal applications.
• Enhanced Process Stability with Thread Forming: The thread forming tapping method creates strong, clean threads without generating chips, leading to a more secure and vibration-resistant joint.

Professional Applications & Engineering Value

This self-drilling wood screw is engineered to solve common assembly challenges in construction, metal framing, and woodworking. The corrosion-resistant coated steel construction prevents rust and degradation, which is critical for both indoor and outdoor applications. Its advanced tip geometry, featuring a 1/2" drill tip and cutting wings, allows it to drill, tap, and fasten in a single operation, drastically reducing labor time and the risk of material splitting. This is particularly valuable when fastening sheet metal to wood, as it eliminates the need for pilot holes and separate tapping steps, ensuring a streamlined, efficient, and professional result for contractors and fabricators.

Specification Summary & Compliance
