S-99461A981 Length 16 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in various environments without rust or degradation.
• Efficient thread forming design (TRS type) creates strong, permanent threads in plastic materials, eliminating the need for pre-tapped holes and reducing assembly time.
• Optimized for plastic applications with a blunt tip and fully threaded shank, minimizing material stress and preventing cracking during installation.
• Quick and secure installation using a standard No. 2 Phillips drive, providing excellent torque transfer and reducing the risk of cam-out for consistent fastening.
• Precise metric sizing (M5 x 16mm with 2.24mm pitch) ensures accurate fit and reliable performance in industrial plastic assemblies.
• Compliance with environmental regulations including RoHS 3 and REACH, making these screws suitable for global markets and sensitive applications.
• Durable pan head design with 8.8mm diameter offers a low-profile, rounded finish that distributes clamping force evenly and resists loosening.

Professional Applications & Engineering Value

These M5 thread forming screws are specifically engineered to address common challenges in plastic fastening, such as material brittleness and strip-out risks. The 18-8 stainless steel provides excellent strength and corrosion resistance, ideal for outdoor equipment, electronic enclosures, and automotive components where moisture or chemicals are present. The TRS (Thread Rolling Screw) design forms threads by displacing plastic material rather than cutting it, resulting in higher pull-out strength and vibration resistance. With a No. 2 Phillips drive and 16mm length, installation is swift and reliable, reducing labor costs in high-volume production. This combination of metric precision and durable materials ensures secure, long-lasting assemblies in plastics like ABS, nylon, or polycarbonate, minimizing failure risks in critical applications.

Specification Summary & Compliance

These screws feature M5 metric threading with an approximate 2.24mm pitch and fully threaded shank for consistent engagement. Manufactured to standard dimensional tolerances for thread forming screws, they are designed for use with a No. 21 drill bit (0.159") in plastic substrates. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring they are free of restricted hazardous substances and suitable for industrial and consumer products requiring environmental safety.
