S-90090A291 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Excellent holding power in sheet metal due to thread forming technology, which creates strong, secure threads without pre-tapping.
• Streamlined installation process with a pointed tip and fully threaded design for quick, easy driving and reduced assembly time.
• Secure, tamper-resistant fastening provided by the one-way drive style, preventing unauthorized removal in critical applications.
• Broad compatibility with a standard 3/16" drill bit, simplifying tooling requirements and inventory management.
• Durable pan head design offers a low-profile, rounded finish for a clean appearance and effective clamping force distribution.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This thread forming tapping screw is specifically engineered for sheet metal applications, where its 18-8 Stainless Steel material provides exceptional resistance to rust and corrosion, extending service life in demanding conditions. The thread forming (or tapping) method displaces material to create strong internal threads, eliminating the need for separate tapping operations and reducing the risk of thread stripping. This is particularly valuable in high-volume assembly lines, as it speeds up production while ensuring a secure, vibration-resistant fit. The fully threaded design and pointed tip facilitate quick alignment and penetration, making it ideal for fastening thin gauge metals, HVAC components, and electronic enclosures where reliability and efficiency are paramount.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a size of No. 12, thread diameter of 0.216", and 11 threads per inch, ensuring precise fit and interchangeability. It is fully threaded and features a right-hand thread direction with a pan head and one-way drive for secure installation. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environments with strict environmental and safety standards.
