Key Features & Benefits at a Glance
- Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding environments.
- Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and tooling costs.
- Reliable Phillips No. 2 drive ensures common tool compatibility and secure installation with reduced cam-out risk.
- Optimized for plastic substrates with a blunt tip and fully threaded shank to prevent material cracking and ensure maximum holding power.
- Precise No. 21 drill bit pairing ensures proper hole sizing for secure thread engagement and vibration resistance.
- Full regulatory compliance with RoHS 3 and REACH standards, making them suitable for global industrial and consumer product applications.
- Standard pan head profile provides a low-profile, finished appearance with good bearing surface for consistent clamping force.
Professional Applications & Engineering Value
These No. 10 x 1/2" 410 stainless steel tapping screws are specifically engineered for plastic fastening applications where material integrity is paramount. The thread forming (DST) technology displaces plastic material rather than cutting it, creating zero chip generation and stronger thread engagement that resists loosening under vibration. The fully threaded design with 16 TPI provides maximum pull-out strength across the entire fastener length, while the blunt tip prevents stress concentration that could lead to plastic cracking. Ideal for electronics enclosures, automotive trim, and consumer products, these Phillips drive screws deliver reliable performance in assembly lines where speed and reliability are critical.
Specification Summary & Compliance
This thread forming screw features a No. 10 size with 1/2" length, 0.19" thread diameter, and 16 threads per inch in right-hand direction. Manufactured to DST tapping screw standards with Class 2A thread tolerances for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance.
