S-90190A242 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Excellent thread-forming capability for secure, vibration-resistant fastening in sheet metal without pre-tapped holes.
• Optimized for high-efficiency installation using a No. 2 Phillips drive, reducing tool slippage and assembly time.
• Maximum material penetration and holding power with a fully threaded, pointed tip design for reliable sheet metal connections.
• Wide compatibility with standard No. 21 drill bits, ensuring precise fit in materials up to 0.025" thickness.
• Compliance with global environmental and safety standards including RoHS 3 and REACH, supporting responsible manufacturing.
• Consistent performance through standardized A/AB thread design with 12 threads per inch for uniform clamping force.

Professional Applications & Engineering Value

Engineered for sheet metal applications, these zinc-plated steel tapping screws address common industrial challenges such as material stripping and loosening under vibration. The thread forming technology creates strong, permanent threads in ductile metals, eliminating the need for separate tapping operations and reducing assembly costs. The Phillips pan head provides a low-profile, secure drive that sits flush against surfaces, while the fully threaded shank ensures uniform stress distribution. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws deliver reliable performance in high-stress environments where durability and compliance with RoHS and REACH standards are critical for industrial safety and longevity.

Specification Summary & Compliance

This No. 10-12 x 1/2" tapping screw features a 0.19" thread diameter with 12 threads per inch, conforming to standard thread forming (Type A/AB) specifications for right-hand threading. Manufactured to precise dimensional tolerances, it ensures consistent fit and performance with a maximum drilling thickness of 0.025" using a No. 21 drill bit. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing adherence to environmental and health safety standards in industrial fastener applications.
