• Optimal flush installation thanks to the standard flat head and 82° countersink angle, providing a smooth, professional finish.
• Enhanced driving control with the Phillips No. 2 drive, reducing cam-out and ensuring secure, efficient installation.
• Full-length threading maximizes grip and load distribution across the entire 1 3/4" length for superior holding power.
• Precision compatibility with No. 32 drill bits and 0.025" maximum drilling thickness, ensuring accurate and reliable fastening in sheet metal.
• Regulatory peace of mind with compliance to RoHS 3 and REACH, meeting strict environmental and safety standards.

Professional Applications & Engineering Value

These No. 6-18 thread forming screws are expertly engineered for sheet metal applications, where material integrity and fastener reliability are critical. The 18-8 stainless steel provides excellent resistance to corrosion and oxidation, making these Phillips flat head screws suitable for outdoor, marine, or industrial settings. The Type A tapping method and fully threaded design ensure that the screw forms a tight, durable thread in the metal, reducing the risk of stripping and improving vibration resistance. This is particularly valuable in assemblies requiring repeated stress or thermal cycling. The 82° countersink angle allows the head to sit flush, preventing snagging and enhancing aesthetic appeal in finished products like HVAC systems, electronic enclosures, and automotive panels. By combining precise dimensions with robust materials, these screws minimize installation time and maximize long-term performance in demanding metalworking projects.

Specification Summary & Compliance
