Key Features & Benefits at a Glance
- Eliminates pre-drilling with integrated drilling tip and cutting wings for faster installation in wood and sheet metal.
- Superior corrosion resistance provided by the zinc plating, ensuring long-term durability in various environments.
- High-strength fastening in wood (0.75"-2.25") and sheet metal (0.11"-0.375") due to the robust steel construction and coarse UNC thread.
- Effortless installation with the Phillips No. 3 drive, reducing cam-out and tool slippage for a secure fit.
- Maximum grip and pull-out resistance from the fully threaded, thread-forming design that creates strong, lasting connections.
- Flush, low-profile finish with the standard flat head, ideal for applications where a smooth surface is required.
- Compliant with environmental standards (RoHS 3), making them a responsible choice for professional and industrial use.
Professional Applications & Engineering Value
These 1/4-20 self-drilling wood screws are engineered to solve common fastening inefficiencies in construction and fabrication. The zinc plated steel body resists rust, while the cutting wings and specialized drilling tip efficiently displace material, eliminating the need for separate pilot holes in sheet metal and wood. This thread-forming UNC coarse thread ensures a tight, vibration-resistant hold, significantly reducing installation time and labor costs. The fully threaded design and flat head provide a secure, flush finish, making these screws a high-value solution for framing, decking, and metal building assemblies where speed and reliability are critical.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with a standard Class 2A tolerance for consistent performance. It is manufactured from zinc plated steel with a Phillips No. 3 drive and a standard flat head profile. The product is fully compliant with RoHS 3 (2015/863/EU) regulations, ensuring it meets strict environmental and safety standards for hazardous substances.
