S-98273A225 8-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping capability eliminates the need for pre-tapped holes, reducing installation time and labor costs in brass, cast iron, and sheet metal applications.
• 410 Stainless Steel construction provides excellent corrosion resistance, ensuring long-term reliability and durability in demanding industrial environments.
• Coarse UNC thread design offers superior holding power and faster installation in a variety of base materials.
• Phillips No. 2 drive ensures common tool compatibility and efficient torque transfer, minimizing cam-out and screw head damage.
• Fully threaded blunt tip design allows for precise starting and controlled thread cutting, reducing material splitting and improving joint integrity.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and unrestricted use in global markets.
• Standard pan head profile with a rounded underside provides a low-profile, finished appearance and good bearing surface.

Professional Applications & Engineering Value

These 8-32 UNC thread cutting screws are engineered to solve critical fastening challenges in metalworking and fabrication. The thread cutting (Type 23/T) design and coarse thread spacing enable them to form strong, precise threads in brass, cast iron, and sheet metal without pre-tapping, significantly speeding up assembly lines. Manufactured from 410 Stainless Steel, they resist corrosion and oxidation, making them ideal for applications exposed to moisture or harsh conditions. The combination of a Phillips No. 2 drive and a blunt tip ensures easy startup and reduces the risk of cross-threading, providing reliable, vibration-resistant joints that maintain integrity under stress, ultimately lowering maintenance costs and enhancing product lifespan.

Specification Summary & Compliance

This screw features a No. 8-32 UNC coarse thread with a Class 2A fit for standard tolerance, ensuring broad compatibility. The fully threaded shank and 1/2" length provide consistent grip. It is designed for use with a No. 26 drill bit (0.147" diameter) for pilot holes. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for industrial use.
