S-98273A165 6-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Efficient self-tapping installation with Type 23/T thread cutting design, reducing the need for pre-tapped holes and speeding up assembly in brass, cast iron, and sheet metal.
• Reliable drive engagement from the Phillips No. 2 drive and pan head, providing secure torque application and minimizing cam-out risks.
• Excellent holding power due to UNC coarse threading and full threading along the 1/2" length, ensuring strong, vibration-resistant fastening.
• Wide material compatibility for use in brass, cast iron, and sheet metal applications, paired with a No. 31 drill bit for precise pilot holes.
• Compliance with environmental standards, meeting RoHS 3 and REACH regulations for safe, sustainable use in global markets.
• Durable, rounded pan head profile that sits flush on surfaces, enhancing aesthetics and preventing snagging in assembled products.

Professional Applications & Engineering Value

These 410 stainless steel tapping screws are engineered to address common challenges in metalworking and assembly, such as material fatigue and installation time. The thread cutting Type 23/T design with UNC coarse threads allows for easy, secure fastening in tough materials like brass, cast iron, and sheet metal, eliminating the need for separate tapping operations and reducing labor costs. The Phillips pan head ensures straightforward driving with standard tools, while the fully threaded shank provides consistent grip along the entire length, minimizing loosening under vibration. Ideal for industrial machinery, automotive components, and electrical enclosures, these screws deliver reliable performance in corrosive environments, supported by their compliance with RoHS and REACH standards for environmental safety.
