S-90434A153 Length 16 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior Holding Power in Plastic: TRS thread forming design creates strong, permanent threads in plastic materials without chipping or cracking, ensuring reliable long-term assemblies.
• Enhanced Corrosion Resistance: The zinc-plated steel construction provides a protective barrier against rust and corrosion, extending the screw's service life in various environments.
• Optimized for Efficient Assembly: The combination of a Phillips No. 1 drive and a standard 90° flat head allows for quick, countersunk installation and a flush finish, speeding up production lines.
• Pre-Engineered Compatibility: Designed for use with a standard 2.25 mm drill bit, these screws simplify the pre-drilling process and reduce the risk of installation errors in plastic components.
• Full-Length Thread Engagement: Being fully threaded along the 16mm length ensures maximum grip and distributes clamping force evenly, preventing loosening under vibration.
• Compliance and Safety Assurance: Meets RoHS 3 and REACH compliance standards, guaranteeing they are free from hazardous substances for use in sensitive and regulated industries.

Professional Applications & Engineering Value

These M3 x 16mm thread forming screws are precision-engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The TRS (Thread Rolling Screw) design displaces plastic material during installation rather than cutting it, which creates a stronger, more vibration-resistant thread with a higher pull-out force. This is critical for applications in electronics enclosures, automotive trim, and consumer goods where zinc-plated steel provides the necessary durability without compromising the integrity of the plastic substrate. The Phillips drive and flat head profile ensure a secure, flush fit, making them ideal for automated assembly processes and enhancing the overall aesthetic and functional quality of the final product.

Specification Summary & Compliance

This fastener features an M3 metric size with an approximate thread pitch of 1.34 mm and a 16 mm length. It is manufactured as a fully threaded, right-hand thread forming screw with a blunt tip. The screw conforms to standard dimensional expectations for tapping screws used in plastic. This product is explicitly verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental and safety regulations for industrial use.
