S-99461A214 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in demanding environments.
• Eliminates the need for pre-tapped holes through advanced thread-forming Tri-Lobe shank design, reducing assembly steps and labor costs.
• Enhanced driving efficiency with a No. 2 Phillips pan head, providing secure tool engagement and reducing cam-out risks.
• Optimal thread engagement and holding power in plastic materials due to the fully threaded, right-hand TRS design with 14 threads per inch.
• Reduced risk of material cracking with a blunt tip and thread-forming tapping method, ideal for delicate plastic assemblies.
• Streamlined installation process using a standard No. 21 drill bit (0.159" diameter), ensuring precise and quick hole preparation.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated industrial applications.

Professional Applications & Engineering Value

This No. 10-14 TRS tapping screw is specifically engineered for plastic fastening applications, where traditional screws may strip threads or cause material stress. The 18-8 Stainless Steel offers excellent resistance to rust and chemicals, while the Tri-Lobe shank cross-section and thread-forming technology create strong, permanent threads in plastics without pre-tapping. This design minimizes assembly time and tooling requirements, making it ideal for high-volume production in electronics, automotive trim, and consumer goods. The Phillips pan head ensures a flush finish and reliable drive performance, reducing rework and improving overall industrial assembly efficiency.

Specification Summary & Compliance

This screw features a No. 10-14 thread size with a 1/4" length, fully threaded right-hand design, and a Class 2A inch-system tolerance for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use. The thread-forming TRS type and specified No. 21 drill bit size (0.159" diameter) provide precise installation guidance for reliable, repeatable results in plastic components.
