Professional Applications & Engineering Value

These 316 stainless steel tapping screws are specifically engineered for sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for pre-tapped holes, creating strong, permanent threads that resist vibration loosening and provide superior pull-out strength. The fully threaded design ensures maximum engagement in materials up to 0.025" thickness, while the oval head profile offers a clean, finished appearance that sits flush with the surface. Ideal for marine, chemical processing, and outdoor industrial equipment, these Phillips drive screws maintain their integrity in corrosive environments where ordinary fasteners would fail prematurely.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.242" thread diameter and 10 threads per inch, these tapping screws feature right-hand threading and standard oval head profile with 82° countersink angle. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet the latest environmental and safety standards for industrial applications. Designed for use with 5.5 mm drill bits (0.2165" diameter), these thread forming screws provide reliable performance in various sheet metal thicknesses while maintaining consistent quality and dimensional accuracy.
