Professional Applications & Engineering Value
This No. 6 x 3/8" 18-8 Stainless Steel Phillips Flat Head Tapping Screw is engineered specifically for sheet metal applications, where material integrity and corrosion resistance are critical. The Type A thread forming design eliminates the need for a separate tapping operation, reducing assembly time and labor costs while creating strong, permanent threads that resist loosening under vibration. The flat undercut head with an 82° countersink angle sits flush with the surface, preventing snagging and providing a clean, aerodynamic profile. Made from durable 18-8 stainless steel, these screws offer excellent resistance to rust and corrosion, making them ideal for outdoor equipment, HVAC systems, and electronic enclosures. Compatible with a No. 32 drill bit (0.116" diameter), they ensure precise, hassle-free installation in industrial settings.
Specification Summary & Compliance
This screw features a thread diameter of 0.138" with 18 threads per inch and is fully threaded for consistent performance. It adheres to standard inch measurements and is designed for right-hand thread direction. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
