S-90485A458 Length 25 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or demanding industrial environments.
• Excellent holding power in plastic due to the thread forming (TRS) design, which creates strong, reliable threads without pre-tapping.
• Efficient and secure installation with the Phillips No. 2 drive, reducing cam-out and ensuring a flush finish with the standard flat head.
• Full 25mm thread engagement provides maximum grip and distribution of stress for enhanced joint integrity.
• Precision 1.57mm thread pitch ensures consistent, vibration-resistant fastening in various plastic materials.
• Compliance with RoHS 3 and REACH standards guarantees environmental safety and material reliability for global supply chains.
• Optimized for use with No. 34 drill bits, simplifying the installation process and reducing assembly time.

Professional Applications & Engineering Value

These M3.5 x 25mm tapping screws are specifically engineered for plastic applications, where traditional fasteners may strip or fail. The 18-8 stainless steel material offers excellent resistance to corrosion and oxidation, extending service life in electronics, automotive, and outdoor equipment. The thread forming (TRS) design displaces plastic material during installation, creating a tight, secure fit that resists loosening from vibration and thermal cycling. Combined with the Phillips flat head and precise 1.57mm thread pitch, these screws ensure rapid, reliable assembly while minimizing the risk of damage to delicate plastic components, making them a cost-effective solution for high-volume manufacturing.

Specification Summary & Compliance

This product features a metric M3.5 size with a 25mm length and fully threaded right-hand design. It complies with standard dimensional tolerances for thread forming screws and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no restricted substances are used. The screw is designed for use with a No. 34 drill bit (0.111") and features a 90° countersink angle for a flush installation in plastic materials.
