S-97740A205 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ideal for demanding industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping
• Precision 82° countersink angle ensures flush mounting and clean professional appearance
• Optimized Phillips drive system provides secure tool engagement and reduces cam-out during installation
• Full threading along entire length delivers maximum holding power and vibration resistance
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global market acceptance
• Right-hand threading with standard A/AB profile ensures compatibility with existing tooling and industry practices

Professional Applications & Engineering Value

Engineered specifically for sheet metal applications, these No. 6-18 tapping screws solve critical fastening challenges in metal fabrication and assembly. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger thread engagement. The 410 Stainless Steel composition provides excellent resistance to corrosion and oxidation, ensuring long-term reliability in harsh environments. The Phillips flat head configuration with standard 82° countersink allows for seamless flush mounting, preventing snagging and maintaining aerodynamic surfaces in HVAC, electronics enclosures, and automotive components. These fully threaded screws distribute clamping force evenly, preventing loosening under vibration and thermal cycling common in industrial settings.

Specification Summary & Compliance

This No. 6-18 x 1/2" tapping screw features precision thread forming with A/AB thread profile and right-hand direction. Manufactured to exacting standards with 0.138" thread diameter and 18 threads per inch, it requires a No. 32 drill bit (0.116" diameter) for optimal performance in materials up to 0.025" thickness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
