S-90315A435 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in harsh industrial environments.
• Excellent holding power through thread forming technology, creating secure, vibration-resistant fastenings in sheet metal without pre-tapped holes.
• Effortless installation with Phillips No. 2 drive and pointed tip, reducing assembly time and tool slippage during high-volume production.
• Clean, finished appearance thanks to the standard oval head design, which sits flush with surfaces for a professional look.
• Reliable thread engagement with fully threaded 18 TPI design, providing consistent grip across the entire 1" length in materials up to 0.025" thick.
• Wide compatibility with standard No. 32 drill bits (0.116" diameter) and 82° countersink angles, simplifying integration into existing sheet metal workflows.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making them suitable for global supply chains and regulated industries.

Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming Type A/AB design displaces material rather than cutting it, creating stronger threads that resist loosening under vibration—a common challenge in automotive, HVAC, and electronic enclosure assembly. The fully threaded configuration and 82° countersink angle ensure maximum surface contact and flush mounting, preventing snagging while maintaining aesthetic appeal. With their Phillips No. 2 drive and precise 0.138" thread diameter, these screws deliver reliable performance in high-volume industrial settings, reducing installation errors and improving production efficiency.

Specification Summary & Compliance

This No. 6 x 1" tapping screw features a 0.138" thread diameter with 18 TPI and complies with standard thread forming specifications for Type A/AB. Manufacturing adheres to precise dimensional tolerances, including 0.262" head diameter and standard oval head profile, ensuring consistent fit and function. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and suitability for industrial use worldwide.
