S-90485A455 Length 16 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or chemically exposed environments.
• Excellent thread-forming capability with TRS design creates strong, reliable threads in plastic materials without pre-tapping.
• Secure flush mounting thanks to the standard flat head profile and 90° countersink angle, preventing snagging and providing a clean finish.
• Efficient installation with No. 2 Phillips drive, reducing cam-out and allowing for high-torque application with standard tools.
• Full-length threading (M3.5 x 16mm) ensures maximum grip and holding power throughout the entire fastener length in plastic substrates.
• Environmental compliance with RoHS 3 and REACH regulations, making them safe for various industrial and consumer applications.
• Precision fit with consistent 1.57mm thread pitch and blunt tip for controlled penetration and reduced risk of material cracking.

Professional Applications & Engineering Value

These M3.5 tapping screws are specifically engineered for plastic applications, where traditional fasteners often fail. The 18-8 stainless steel provides exceptional corrosion resistance, crucial for outdoor equipment, automotive components, and electronic enclosures exposed to moisture. The TRS thread forming design displaces plastic material during installation, creating strong, load-bearing threads without chips or debris. This eliminates the need for threaded inserts in many cases, reducing assembly time and component costs. The Phillips flat head with 90° countersink ensures a secure, flush fit that won't protrude, making these metric screws ideal for applications where surface smoothness and safety are priorities.

Specification Summary & Compliance

These M3.5 x 16mm fully threaded screws feature a standard flat head profile with a No. 2 Phillips drive and are designed for use with a No. 34 drill bit (0.111" diameter). The thread forming (tapping method) follows typical TRS screw standards, creating threads in plastic without cutting. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet strict environmental and safety standards for industrial use.
