S-90410A829 10-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping efficiency – Cuts precise threads in pre-drilled holes, eliminating the need for separate tapping operations and reducing assembly time in brass, cast iron, and sheet metal.
• Superior corrosion resistance – Made from 410 stainless steel for reliable performance in demanding industrial environments, resisting rust and degradation.
• Optimized torque transmission – No. 2 Phillips drive ensures secure bit engagement, minimizing cam-out and enabling efficient installation with standard tools.
• Enhanced holding power – Fine UNF thread spacing provides a tighter grip and superior vibration resistance in materials like sheet metal and cast iron.
• Full-thread engagement – Fully threaded design maximizes pull-out strength and distributes load evenly along the entire screw length for secure fastening.
• Regulatory compliance assurance – Meets RoHS 3 and REACH standards, ensuring safety and environmental responsibility for global industrial supply chains.
• Precision compatibility – Designed for use with a No. 21 drill bit (0.159" diameter), ensuring accurate hole preparation and reliable thread formation.

Professional Applications & Engineering Value

These 10-32 UNF thread cutting tapping screws are engineered to solve common assembly challenges in metalworking and fabrication. The Type F thread cutting design and 410 stainless steel construction allow them to form strong, clean threads in brass, cast iron, and sheet metal without pre-tapped holes, significantly reducing labor and tooling costs. The fine thread spacing and fully threaded shank enhance resistance to loosening under vibration, making them ideal for machinery, enclosures, and automotive components. With a No. 2 Phillips drive, they offer reliable installation torque, while their RoHS and REACH compliance ensures they meet stringent industrial and environmental regulations, providing long-term reliability in corrosive or high-stress environments.

Specification Summary & Compliance

This screw features a 10-32 UNF fine thread with a right-hand direction and fully threaded shank, manufactured to standard thread cutting (Type F) specifications for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards. The dimensional accuracy, including the 1/2" length and 0.19" thread diameter, supports precise fit and reliable fastening in industrial applications.
