S-90033A342 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding industrial environments
• Efficient thread forming technology creates stronger, vibration-resistant threads in sheet metal without pre-tapping requirements
• Optimal 82° countersink angle ensures flush mounting and clean professional finishes in sheet metal assemblies
• Full threading with pointed tip provides faster starting and smoother installation with reduced driving torque
• Phillips No. 3 drive system offers secure tool engagement and prevents cam-out during high-torque applications
• Precision dimensional consistency with standardized No. 12 sizing ensures reliable performance and interchangeability
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These black-oxide steel tapping screws are engineered specifically for sheet metal applications where reliability and installation efficiency are critical. The thread forming technology eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger, more durable threads that resist loosening under vibration. The Phillips flat head design with standard 82° countersink angle provides clean, flush finishes in metal fabrication, electronics enclosures, HVAC systems, and automotive components. The black-oxide surface treatment provides essential corrosion protection in industrial environments, while the fully threaded configuration with pointed tip ensures quick starts and smooth penetration through pre-drilled 3/16" holes, minimizing installation effort and improving production throughput.
