Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
- Secure Phillips drive (No. 2) provides reliable torque transmission and prevents cam-out during high-speed assembly operations.
- Standard flat head with 82° countersink sits flush with surfaces for a clean finish and eliminates snagging hazards in machinery.
- Full threading along the 2-1/2" length ensures maximum grip and uniform load distribution across the entire fastened joint.
- Precision-engineered for 0.025" maximum drilling thickness in sheet metal, delivering consistent performance in automated production lines.
- Compliance with RoHS 3 and REACH regulations guarantees environmental safety and global market acceptance for your products.
Professional Applications & Engineering Value
These No. 6-18 thread forming screws solve critical fastening challenges in sheet metal fabrication by combining 18-8 stainless steel durability with optimized geometry. The Phillips flat head design with 82° countersink angle ensures seamless surface integration while the thread forming tapping method eliminates the need for separate tapping operations, significantly reducing assembly time in HVAC systems, electronic enclosures, and automotive panels. The fully threaded shank maintains consistent clamping force across the entire 2-1/2" length, preventing joint loosening under vibration - a common failure point in industrial equipment. Engineered for 0.025" maximum drilling thickness, these screws provide reliable performance in thin-gauge metal applications where strip-out resistance is paramount.
Specification Summary & Compliance
Manufactured to precise dimensional standards with No. 6-18 thread specification (0.138" diameter, 18 TPI) and standard flat head profile. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The thread forming design follows industry-standard Type A tapping screw specifications for consistent performance in sheet metal applications.
