S-90485A449 Length 30 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring longevity in humid or demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in plastic materials without chips, reducing assembly time and cleanup.
• Secure flush mounting with a standard 90° flat head profile and No. 2 Phillips drive, providing a clean finish and preventing snagging.
• Optimized for plastic assembly with a blunt tip and fully threaded M3 x 30mm body, minimizing stress cracking and ensuring reliable grip.
• Precise installation compatibility using a No. 41 drill bit (0.096"), allowing for accurate hole preparation and consistent performance.
• Compliance with environmental regulations including RoHS 3 and REACH, making them safe for use in regulated industries and export markets.
• Right-hand threading with 1.34mm pitch delivers smooth, controlled driving and high pull-out resistance in thermoplastic and soft plastic substrates.

Professional Applications & Engineering Value

These M3 TRS thread forming screws are engineered to address common challenges in plastic assembly, such as material cracking and weak thread retention. The 18-8 stainless steel offers excellent tensile strength and corrosion resistance, ideal for electronics enclosures, automotive trim, and consumer appliances exposed to moisture or chemicals. The flat head with 90° countersink ensures a seamless surface finish, while the Phillips drive allows for efficient torque application without cam-out. By using a thread forming (rather than cutting) method, these screws displace plastic material to form durable, high-strength threads that resist vibration loosening, making them a reliable choice for industrial fastening in thermoplastics and composite materials where disassembly is not required.

Specification Summary & Compliance

This M3 x 30mm TRS tapping screw features a fully threaded shank with an approximate thread pitch of 1.34mm and right-hand direction. It complies with standard metric dimensions and is designed for use with a No. 41 drill bit (0.096" diameter) and a 90° countersink angle. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial applications.
