S-90485A473 Length 35 mm Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments.
• Superior holding power in plastic materials due to thread forming (TRS) design, which displaces material without creating chips for secure, vibration-resistant fastening.
• Efficient installation with Phillips No. 2 drive, providing common tool compatibility and reducing assembly time in industrial settings.
• Optimal flush mounting thanks to the standard flat head profile and 90° countersink angle, ideal for applications requiring a smooth surface finish.
• Full 35mm threading ensures maximum grip length and uniform stress distribution, enhancing joint integrity in plastic assemblies.
• Precise 1.79mm thread pitch delivers fine adjustment control and consistent engagement, minimizing the risk of material stripping.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use across global industrial supply chains.

Professional Applications & Engineering Value

Engineered for plastic fastening applications, the M4 x 35mm TRS tapping screw addresses common challenges like material cracking and loosening under dynamic loads. Its thread forming technology creates strong, permanent threads in thermoplastics and other soft materials by cold-flowing the substrate, eliminating chip formation that can clog machinery or weaken the assembly. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemicals, extending service life in automotive, electronics, and consumer goods industries. Combined with a fully threaded shank and blunt tip, it ensures precise alignment and reduces installation torque, making it a reliable choice for high-volume production lines where consistency and durability are critical.

Specification Summary & Compliance
