Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
  • Efficient thread forming action with Type B design creates strong, permanent threads in sheet metal without chips.
  • Excellent drive stability provided by the Phillips No. 1 drive and pan head, reducing cam-out and ensuring secure installation.
  • Full-length threading maximizes grip and load distribution across the entire 7/8" length for robust assemblies.
  • Precision blunt tip allows for easy alignment and starts threads accurately in pre-drilled No. 44 (0.086") holes.
  • High thread density with 24 threads per inch ensures fine adjustment and a tight, vibration-resistant fit.
  • Compliance with RoHS 3 ensures environmental safety and meets strict international regulatory standards.

Professional Applications & Engineering Value

This Type B thread forming tapping screw is engineered specifically for sheet metal applications, where its 18-8 Stainless Steel composition provides exceptional resistance to rust and oxidation, extending service life in demanding conditions. The thread forming technology displaces material rather than cutting it, resulting in zero swarf and stronger, more reliable threads that resist loosening under vibration. The Phillips pan head and No. 1 drive offer a flush, low-profile finish with improved torque transmission, reducing installation time and tool slippage. Ideal for HVAC, electronics enclosures, and automotive panels, this screw ensures durable, maintenance-free assemblies with consistent performance.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 4-24 thread size, 7/8" length, and fully threaded right-hand design. It meets typical thread forming screw specifications for use with a No. 44 drill bit (0.086" diameter). The product is manufactured to ensure precise fit and is fully RoHS 3 (2015/863/EU) Compliant, confirming it is free of hazardous substances and suitable for global industrial and electronic applications.
