S-99397A673 Length 5 mm Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in various industrial environments.
• Superior torque transmission and reduced cam-out thanks to the Torx Plus IP15 drive, allowing for precise installation and minimizing tool wear.
• Secure fastening in plastic materials through the thread-forming TRS design, which creates strong, durable threads without pre-tapping.
• High pull-out resistance and vibration resistance due to the tri-lobe shank cross-section, providing reliable performance in dynamic applications.
• Easy alignment and consistent seating with the standard pan head profile, facilitating quick assembly and a flush finish.
• Full thread engagement for maximum holding power as the screw is fully threaded, ideal for thin plastic sections.
• Compliance with strict environmental regulations, including RoHS 3 and REACH, ensuring safe use in global markets.

Professional Applications & Engineering Value

This M3.63 zinc-plated steel TRS tapping screw is engineered to address common challenges in plastic assembly, such as strip-out and loosening under stress. The thread-forming design with a tri-lobe shank displaces material to form precise threads, eliminating the need for pre-drilled threads and reducing assembly time. Made from robust zinc-plated steel, it offers excellent corrosion resistance, making it suitable for electronics, automotive components, and consumer appliances where plastic fasteners must endure environmental exposure. The Torx Plus IP15 drive ensures high torque transfer with minimal slippage, enhancing efficiency in automated or manual installations. Ideal for securing plastic housings, panels, and internal structures, this screw delivers reliable, long-lasting performance in demanding industrial applications.

Specification Summary & Compliance

This screw features a metric M3.63 size with an approximate thread pitch of 1.34 mm, a length of 5 mm, and a blunt tip for controlled penetration.
