S-90485A130 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability in plastic assemblies.
• Enhanced holding power due to the Tri-Lobe shank design, which reduces material stress and prevents loosening in plastic applications.
• Efficient thread forming for plastics, creating strong, permanent threads without pre-tapping and minimizing cracking or damage.
• Reliable installation with Phillips drive (No. 1 size) and flat head profile, ensuring secure fastening and a flush finish.
• Full threading along the 3/8" length provides consistent grip and distribution of load across the entire fastener.
• Precision thread design (0.086" diameter, 28 TPI) ensures tight fit and vibration resistance in plastic components.
• Compliance with environmental standards including RoHS 3 and REACH, making them safe for industrial and consumer products.

Professional Applications & Engineering Value

These No. 2 TRS tapping screws are specifically engineered for plastic assembly challenges, where traditional fasteners may cause cracking or stripping. The 18-8 stainless steel material offers excellent durability and resistance to corrosion, extending the life of assemblies in humid or chemical-exposed environments. The thread forming action, combined with the Tri-Lobe shank, displaces plastic material gently to form secure threads, reducing installation torque and preventing stress concentration. This design is ideal for applications in electronics enclosures, automotive plastic parts, and consumer goods, where reliable, vibration-resistant fastening is critical. The Phillips flat head ensures easy drive engagement and a smooth surface finish, enhancing both performance and aesthetics in industrial settings.

Specification Summary & Compliance

This product adheres to standard inch measurements with precise thread dimensions (0.086" diameter, 28 TPI) and a fully threaded design for consistent performance. It meets common industrial requirements for thread forming screws in plastics, with a blunt tip and standard flat head profile (82° countersink angle). Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring they are free of hazardous substances and suitable for global supply chains in sectors like manufacturing and electronics.
