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 with A/AB tapping screw design creates strong, secure threads in sheet metal without pre-tapping, reducing installation time.
  • Secure tamper-resistant installation using the drilled spanner drive, providing a non-slip grip and enhanced control during fastening.
  • Maximum holding power from the fully threaded design, ensuring consistent grip along the entire 1" length for robust assemblies.
  • Precision compatibility with 5.5mm (0.2165") drill bits and up to 0.025" maximum drilling thickness, enabling accurate, repeatable installations.
  • Durable pan head design with standard rounded profile offers a low-profile, aesthetically clean finish while distributing clamp load effectively.
  • Environmental compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These No. 14-10 x 1" 18-8 stainless steel tapping screws are engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The thread forming capability eliminates the need for separate tapping operations, reducing labor and tooling costs while minimizing the risk of cross-threading. Made from 18-8 stainless steel, they resist rust and chemical exposure, ensuring longevity in demanding applications like HVAC systems, electronic enclosures, and automotive panels. The drilled spanner drive provides a secure, tamper-resistant fit, ideal for maintenance-free environments. With a fully threaded shank and pointed tip, these screws deliver uniform clamping force and easy penetration, enhancing assembly speed and structural integrity in thin-gauge metals.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.242" and 10 threads per inch, ensuring precise fit in pre-drilled holes. The Class 2A thread tolerance and right-hand thread direction provide reliable engagement, while the A/AB tapping screw type conforms to industry-accepted forming standards. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the absence of hazardous substances, supporting global environmental and safety requirements for industrial components.
