Key Features & Benefits at a Glance

  • Exceptional corrosion resistance in harsh environments thanks to premium 316 stainless steel construction.
  • Reliable thread-forming performance for secure, vibration-resistant fastening in sheet metal without the need for a pre-tapped hole.
  • Broad compatibility and ease of installation with a standard Phillips drive (No. 1) and recommended No. 44 drill bit.
  • Full-length threading ensures maximum grip and holding power along the entire 1/4" length.
  • Durable pan head design provides a low-profile, rounded finish for a clean appearance and reduced snagging.
  • Compliance with major environmental regulations, including RoHS 3 and REACH, for safe use in regulated industries.
  • Precision-engineered No. 4-24 thread delivers consistent, high-strength fastening for demanding industrial applications.

Professional Applications & Engineering Value

This Type B thread forming screw is specifically engineered to address the challenges of fastening in sheet metal and other ductile materials. The 316 stainless steel material offers superior resistance to corrosion from chemicals, saltwater, and extreme weather, making it ideal for marine, chemical processing, and outdoor equipment. Its thread-forming design displaces material to create strong, wear-resistant internal threads, eliminating the need for tapping and reducing assembly time. The combination of a Phillips pan head and fully threaded shank ensures high clamp load and ease of installation in tight spaces, providing long-term reliability and reducing maintenance costs in industrial settings.

Specification Summary & Compliance

This tapping screw conforms to standard inch measurements with a No. 4-24 thread and a 1/4" length. It is manufactured as a Type B, thread-forming screw with a right-hand thread direction and is designed for use with a No. 44 drill bit (0.086" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial components.
