S-93195A110 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Flush, secure seating with an 82° countersink angle and undercut flat head profile, preventing surface protrusion and providing a clean finish.
• Maximum holding power due to fully threaded design, ensuring consistent grip along the entire fastener length in sheet metal applications.
• Reliable drive engagement with Phillips No. 1 drive, offering widespread compatibility and reducing cam-out risks during installation.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, ensuring safe use in regulated industries and global markets.

Professional Applications & Engineering Value

These Type B thread forming screws are precision-engineered for sheet metal fastening, where material integrity and vibration resistance are critical. The 18-8 Stainless Steel provides excellent strength and corrosion resistance, eliminating rust concerns in demanding environments like HVAC assemblies, electronic enclosures, and automotive panels. The thread forming tapping method displaces material to create strong, load-bearing threads without chips, reducing the risk of loose fittings and maintenance needs. Combined with a Phillips flat head and 82° countersink, they ensure a flush mount that maintains aerodynamic and aesthetic surfaces, making them a reliable choice for high-performance industrial applications.

Specification Summary & Compliance

This No. 4-24 x 1/4" screw adheres to standard inch measurements with a thread diameter of 0.112" and 24 threads per inch, ensuring precise fit in pre-drilled No. 44 (0.086" diameter) holes. Manufactured as a fully threaded, right-hand Type B tapping screw with a blunt tip, it meets industry threading and dimensional tolerances. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms its suitability for environmentally conscious and global industrial use, free from restricted hazardous substances.
