S-96817A204 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with Torx Plus IP6 drive, reducing cam-out and tool wear for reliable fastening in repetitive industrial use.
• Enhanced corrosion resistance from zinc-plated steel construction, ensuring long-term durability in varied environmental conditions.
• Efficient thread forming design for plastic materials, creating strong, vibration-resistant threads without pre-tapping, saving assembly time.
• Full threading with 0.78mm pitch provides consistent grip and uniform load distribution, minimizing stress concentration in plastic components.
• Standard pan head profile offers a low-profile, rounded finish for smooth surface integration and reduced snagging risks.
• Compliance with RoHS 3 and REACH standards ensures environmental safety and regulatory acceptance for global industrial supply chains.
• Blunt tip and right-hand threading enable easy alignment and secure installation, reducing damage to plastic substrates during assembly.

Professional Applications & Engineering Value

This M2 x 4mm zinc-plated steel TRS thread forming screw is engineered to address common challenges in plastic assembly, such as material cracking and thread stripping. The thread forming design displaces plastic material to create durable internal threads, eliminating the need for separate inserts and reducing component count. With a Torx Plus IP6 drive, it delivers high torque efficiency, preventing slippage in automated or high-volume production lines. The zinc-plated finish combats corrosion in humid or industrial environments, extending service life in electronics, automotive trim, and consumer goods. Fully threaded and featuring a 0.78mm pitch, it ensures maximum holding power in brittle or thin plastics, making it ideal for applications requiring vibration resistance and repeated disassembly.

Specification Summary & Compliance

This screw adheres to metric standards with an M2 size, 4mm length, and fully threaded 0.78mm pitch for precise fit. The Torx Plus T6 drive and pan head design comply with industrial drive specifications, while the thread forming (TRS) style is optimized for plastic substrates. Manufactured from zinc-plated steel, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring no restricted substances are used. Dimensions include a head diameter of 3.35mm and head height of 1.6mm, supporting consistent performance in automated fastening systems.
