• Maximum holding power through fully threaded design ensures secure fastening across the entire screw length
• Quick installation with No. 3 Phillips drive providing reliable torque transfer and reduced cam-out risk
• Versatile material compatibility specifically engineered for use in brass, cast iron, and sheet metal applications
• Reliable coarse threading with 1/4"-20 UNC profile delivers strong pull-out resistance in various substrates
• Environmental compliance meeting RoHS 3 and REACH regulations for global manufacturing requirements

Professional Applications & Engineering Value

These 1/4-20 UNC thread cutting tapping screws in 410 stainless steel solve critical fastening challenges in industrial assembly operations. The Type 23/T thread cutting design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in brass, cast iron, and sheet metal applications. The coarse UNC threading provides exceptional pull-out resistance while the fully threaded configuration ensures uniform stress distribution. With Phillips drive compatibility and blunt tip design, these screws offer controlled penetration depth and prevent material splitting, making them ideal for precision assembly in electrical enclosures, machinery frames, and metal fabrication projects where reliability and corrosion resistance are paramount.

Specification Summary & Compliance
