S-90380A271 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the thread-forming Tri-Lobe shank design that displaces material without creating chips.
• Enhanced corrosion resistance provided by the zinc-plated steel construction, ensuring long-term durability in various environments.
• Efficient and secure installation with the No. 1 Phillips drive and standard pan head, reducing cam-out and speeding up assembly.
• Maximum fastening strength from the fully threaded design, offering consistent grip along the entire 3/4" length.
• Reliable performance in plastic assemblies due to the blunt tip and right-hand threads, minimizing the risk of material splitting.
• Compliance with industrial safety standards including RoHS 3 and REACH, ensuring safe use in regulated applications.
• Precise fit with recommended No. 43 drill bit (0.089" diameter), facilitating accurate hole preparation for optimal thread engagement.

Professional Applications & Engineering Value

This No. 3 x 3/4" zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic fastening, such as material cracking and weak thread retention. The thread-forming Tri-Lobe shank creates strong, load-bearing threads in plastic by compressing the material, eliminating the need for pre-tapped holes and reducing assembly time. Its fully threaded design ensures uniform stress distribution, preventing loosening under vibration. Ideal for industrial applications in electronics, automotive components, and consumer goods, this Phillips drive screw offers reliable performance while meeting stringent RoHS and REACH compliance for environmental safety.

Specification Summary & Compliance

This screw features a thread diameter of 0.099" with 24 threads per inch and a fully threaded length of 3/4", adhering to standard inch measurements. It is designed for use with a No. 43 drill bit (0.089" diameter) for precise hole preparation. The zinc-plated steel construction ensures durability, and the product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial and consumer applications without hazardous substances.
