- Optimized for plastic assembly with a blunt tip design that minimizes material stress and prevents cracking during installation.
- Secure and stable fastening from the fully threaded shank, providing maximum grip and vibration resistance in plastic substrates.
- Easy installation and removal with the Phillips No. 1 drive, ensuring compatibility with standard tools and reducing assembly time.
- Precision fit with a recommended No. 44 drill bit (0.086" diameter), ensuring clean thread formation and consistent performance.
- Compliance with environmental standards, meeting RoHS 3 and REACH regulations for safe and sustainable use.
Professional Applications & Engineering Value
These 18-8 stainless steel tapping screws are specifically engineered for plastic fastening applications, where traditional screws may strip threads or cause material failure. The DST thread forming design displaces plastic material to create strong, load-bearing internal threads, eliminating the need for inserts and reducing assembly steps. The blunt tip and fully threaded configuration ensure smooth entry and uniform stress distribution, preventing cracking in brittle plastics like ABS, polycarbonate, and nylon. With a Phillips pan head for low-profile, secure seating, these screws provide reliable performance in electronics enclosures, automotive trim, and consumer goods, enhancing durability and assembly efficiency in industrial settings.
Specification Summary & Compliance
This No. 4-24 x 3/8" screw features a right-hand thread with approximately 24 threads per inch and a rounded pan head profile. Manufactured from 18-8 stainless steel, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. The screw is designed for use with a No. 44 drill bit (0.086" diameter) and follows standard inch system measurements for precise fit in plastic components.
