Professional Applications & Engineering Value
This No. 10-16 x 1/2" stainless steel tapping screw is specifically engineered for plastic fastening applications where material integrity and long-term performance are critical. The thread-forming DST design eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, permanent threads that resist loosening under vibration. The 18-8 stainless steel material provides excellent corrosion resistance, making these screws ideal for outdoor equipment, electrical enclosures, and automotive components where environmental exposure is a concern. The Phillips pan head combines easy installation with a low-profile appearance, while the fully threaded design ensures maximum holding power throughout the entire engagement length in plastic substrates.
Specification Summary & Compliance
This tapping screw features a No. 10-16 thread size with Class 2A tolerance, 1/2" length, and right-hand thread direction. Manufactured to industry standards for thread-forming screws with DST (Thread Forming Tapping Screw) specification. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use across various sectors.
