S-95829A205 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced Security: Tamper-resistant hex drive prevents unauthorized removal, ideal for public or high-security installations.
• Superior Corrosion Resistance: Made from 18-8 Stainless Steel for excellent durability in harsh or humid environments.
• Strong Thread Engagement: Thread forming design creates robust, permanent threads in sheet metal without pre-tapping, reducing assembly steps.
• Flush, Professional Finish: Flat head with a standard 82° countersink angle sits seamlessly in materials for a smooth surface and reduced snagging.
li>Optimized for Sheet Metal: Specifically designed for use in sheet metal up to 0.025" thick, ensuring reliable fastening in thin materials.
• Full-Length Threading: Fully threaded shank provides maximum grip and holding power along the entire screw length.
• Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring they are safe for use in regulated industries and environmentally conscious supply chains.

Professional Applications & Engineering Value

This No. 8-15 x 1/2" Tamper-Resistant Hex Flat Head Tapping Screw is engineered to solve critical challenges in sheet metal assembly. Its 18-8 Stainless Steel construction provides inherent resistance to rust and corrosion, which is vital for outdoor enclosures, HVAC systems, and electronic casings exposed to moisture. The thread forming (Type A/AB) design eliminates the need for a separate tapping operation, as it cold-forms strong, clean threads directly into the material, reducing labor time and preventing chip accumulation. The tamper-resistant hex drive (5/32") offers a significant security advantage, deterring vandalism and unauthorized access in public infrastructure, telecommunications, and secured machinery. Combined with a precise 82° countersink angle, it ensures a flush fit that minimizes protrusion risks and maintains aerodynamic or aesthetic surfaces in fabricated metal products.

Specification Summary & Compliance

This screw conforms to standard inch measurements with a No. 8 screw size, 0.164" thread diameter, and 15 threads per inch. The flat head features a diameter of 0.359" and is designed for use with a No. 29 drill bit (0.136" diameter). It is a right-hand threaded, fully threaded tapping screw of Type A/AB. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial applications.
