S-95893A215 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission and reduced cam-out with the Torx Plus IP8 drive, ensuring efficient installation and longer tool life.
• Excellent corrosion resistance provided by the zinc-plated steel material, enhancing durability in various industrial environments.
• Strong, reliable thread formation in plastic materials due to the TRS thread forming design and tri-lobe shank, which maximizes pull-out strength and vibration resistance.
• Flush, professional finish with the standard flat head and 82° countersink angle, preventing snagging and ensuring a smooth surface.
• Simplified installation process as these screws are fully threaded and designed for use with a No. 44 drill bit, reducing preparation time and errors.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and meeting global supply chain requirements.
• Consistent performance and interchangeability thanks to precise inch system measurements and standardized right-hand threading.

Professional Applications & Engineering Value

These No. 4 zinc-plated steel TRS tapping screws are specifically engineered for plastic applications, where traditional fasteners may strip or fail. The thread forming method and tri-lobe shank cross-section create strong, lasting threads in plastic substrates without pre-tapping, eliminating the need for inserts and reducing assembly costs. The Torx Plus IP8 drive delivers high torque transfer with minimal slippage, crucial for automated production lines and repetitive tasks. Combined with a flat head and 82° countersink, these screws provide a secure, flush fit that resists loosening under vibration, making them ideal for electronics enclosures, automotive trim, and consumer appliances where reliability and aesthetics are paramount.

Specification Summary & Compliance

This screw features a No. 4 size with a thread diameter of 0.112" and approximately 20 threads per inch, ensuring precise fit in plastic components. It is fully threaded with a blunt tip and right-hand direction for standard use. Manufactured to consistent inch system tolerances, it is designed for a No. 44 drill bit (0.086" diameter). The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety standards for industrial applications.
