S-90485A413 Length 8 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 demanding environments.
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and tooling costs.
• Secure flush mounting with a standard 90° flat head profile that sits perfectly countersunk in plastic components for a clean, professional finish.
• Optimized drive engagement using a No. 0 Phillips drive style, providing excellent torque transfer and minimizing cam-out during installation.
• Full-length threading (M1.6 x 8mm) ensures maximum grip and holding power across the entire screw length in plastic substrates.
• Precision compatibility with No. 55 drill bits (0.052" diameter), enabling quick, accurate hole preparation for consistent performance.
• Environmental compliance assurance meeting RoHS 3 and REACH standards, making them safe for global industrial and consumer applications.

Professional Applications & Engineering Value

These M1.6 TRS tapping screws are engineered specifically for plastic fastening applications, where traditional screws may strip threads or cause material stress cracks. The thread forming (TRS) design displaces plastic material during installation, creating a tight, vibration-resistant fit that eliminates the need for inserts or adhesives. Manufactured from 18-8 Stainless Steel, they resist oxidation and chemical exposure in electronics enclosures, automotive trim, and consumer goods. The Phillips flat head with 90° countersink angle provides a seamless finish while the 0.67mm thread pitch ensures fine adjustment control. Ideal for high-volume production environments requiring reliable plastic assembly solutions with minimal failure rates.

Specification Summary & Compliance

This metric TRS tapping screw features M1.6 x 8mm dimensions with fully threaded shank and blunt tip. The 3mm head diameter and 0.96mm head height conform to standard flat head profiles. Manufactured to precise thread forming specifications with right-hand threading and 0.67mm approximate pitch. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
