S-90485A465 Length 12 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or chemically exposed environments.
• Excellent thread-forming capability for plastic materials, creating strong, permanent threads without pre-tapping and reducing assembly time.
• Secure and flush installation thanks to the flat head design and 90° countersink angle, providing a smooth surface finish and preventing snagging.
• Efficient drive engagement with Phillips No. 2 drive, allowing for quick installation with standard tools and minimizing cam-out risks.
• Optimized thread pitch of 1.79mm ensures high pull-out resistance and vibration resistance in plastic substrates.
• Fully threaded shank maximizes grip length and distributes load evenly, enhancing holding power in plastic applications.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and suitability for global industrial markets.

Professional Applications & Engineering Value

These M4 x 12mm tapping screws are specifically engineered for plastic fastening challenges, where traditional screws may strip or loosen. Made from 18-8 stainless steel, they resist rust and corrosion, ideal for outdoor equipment, electronic enclosures, and automotive components. The thread forming (TRS) design displaces plastic material during installation, creating a tight, secure fit that withstands vibration and thermal cycling. With a Phillips flat head and standard profile, they ensure a clean, flush finish in countersunk holes, reducing assembly errors. These screws are perfect for applications in consumer electronics, HVAC systems, and industrial machinery, providing reliable performance without the need for additional inserts or adhesives.

Specification Summary & Compliance

This product adheres to standard metric dimensions with an M4 screw size, 12mm length, and approximate thread pitch of 1.79mm. The thread forming tapping method and fully threaded design comply with common industrial practices for plastic substrates. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are used. The flat head features a 90° countersink angle for precise fit, and the drive style is Phillips No. 2, supporting efficient installation with standard tools.
