S-99461A963 Length 6 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Efficient thread forming design (TRS type) creates strong, permanent threads in plastics without pre-tapping, reducing assembly time and tooling costs.
• Secure, slip-resistant fastening with a Phillips No. 1 drive and pan head, ensuring consistent torque application and preventing cam-out during installation.
• Maximum holding power due to fully threaded M4 x 6mm design, providing uniform load distribution and vibration resistance in plastic assemblies.
• Broad material compatibility for various plastics, with a blunt tip and standard pan head profile to prevent material cracking and ensure flush mounting.
• Regulatory compliance with RoHS 3 and REACH standards, ensuring safe, environmentally responsible use in industrial and consumer products.
• Metric precision with consistent M4 threading and 6mm length, enabling reliable interchangeability and simplified inventory management.

Professional Applications & Engineering Value

These M4 TRS thread forming screws are engineered to address common challenges in plastic assembly, such as stress cracking and stripped threads. The 18-8 stainless steel material offers excellent strength and corrosion resistance, while the thread forming (TRS) design displaces plastic material to create robust, load-bearing threads without chips or debris. This eliminates the need for pre-drilled threads, streamlining production and reducing part failure in applications like electronics enclosures, automotive components, and consumer appliances. The Phillips drive and pan head provide reliable installation with standard tools, ensuring consistent clamp load and vibration resistance in dynamic environments.

Specification Summary & Compliance

This M4 x 6mm screw features a fully threaded metric design with a blunt tip and standard pan head (7mm diameter, 2.8mm height). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use. The thread forming (TRS) tapping method is optimized for plastics, requiring a No. 30 drill bit (0.1285" diameter) for proper installation and secure fastening.
