S-96817A311 Length 4 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability creates strong, permanent threads in plastic materials without generating chips, ensuring clean installations and reducing assembly defects.
• High-torque T6 Torx drive provides excellent cam-out resistance for more efficient driving and reduced tool wear, speeding up production cycles.
• Durable zinc-plated steel construction offers reliable corrosion resistance, extending the service life of your assemblies in various environments.
• Integrated flange on the pan head distributes clamping force over a wider area, preventing damage to soft plastic surfaces and providing a more secure hold.
• Fully threaded blunt tip design allows for easier starting and controlled engagement in pre-drilled holes, minimizing the risk of material splitting.
• Precision M2 x 4mm metric sizing with a consistent 0.89 mm pitch ensures a perfect fit and reliable performance in compact electronic and plastic assemblies.
• Compliance with major environmental regulations guarantees that your products meet global standards for hazardous substances, simplifying supply chain management.

Professional Applications & Engineering Value

This M2 tapping screw is engineered specifically for plastic fastening applications, where traditional screws can cause cracking or stripping. The thread forming (TRS) design displaces material to create a zero-clearance fit, resulting in higher pull-out strength and vibration resistance compared to thread-cutting alternatives. Made from robust zinc-plated steel, it provides the necessary durability for consumer electronics, automotive trim, and appliance assemblies. The T6 Torx drive is critical for high-volume manufacturing, allowing operators to apply greater torque without slippage, which reduces assembly time and improves repeatability. The flanged pan head offers a low-profile, wide bearing surface that is ideal for securing thin plastic panels without sink marks, making it a versatile choice for designers seeking reliability and a clean aesthetic finish.

Specification Summary & Compliance

This screw conforms to standard metric (M2 x 4mm) dimensions with an approximate thread pitch of 0.89 mm and is fully threaded for maximum grip. It features a Class 2A tolerance for general-purpose use and is designed for use with a drill bit size #58 (0.042") for optimal performance in plastic. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances for global market acceptance.
