• Optimized for Sheet Metal: The No. 8 size and pointed tip ensure easy starting and strong holding power in sheet metal assemblies.
• Flush, Professional Finish: Flat head with an 82° countersink angle sits flush for a smooth surface and improved aesthetics.
• Streamlined Installation: Compatible with a standard No. 29 drill bit (0.136" diameter) for precise and efficient hole preparation.
• Environmental & Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring safety and regulatory adherence for global markets.

Professional Applications & Engineering Value

This tamper-resistant hex flat head tapping screw is engineered to address critical challenges in sheet metal fabrication and assembly. Its 18-8 Stainless Steel construction provides exceptional resistance to rust and corrosion, making it suitable for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. The thread forming (Type A/AB) design displaces material to form strong internal threads, eliminating the need for a separate tapping operation and reducing the risk of strip-out in thin-gauge metals. The tamper-resistant drive adds a layer of security, preventing vandalism or tampering in public infrastructure, transportation, and access panels. With a fully threaded shank and pointed tip, it ensures rapid installation and high clamp load, delivering reliable performance in demanding industrial applications.

Specification Summary & Compliance

This screw conforms to standard inch dimensions: No. 8 size with a 0.164" thread diameter and approximately 15 threads per inch. The flat head features a standard profile with an 82° countersink angle and is designed for use with a 5/32" tamper-resistant hex drive. It is manufactured as a thread forming tapping screw (Type A/AB) for use in materials up to 0.025" thickness and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
