S-91775A718 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel finish, extending service life in demanding industrial environments
• Exceptional thread retention through thread forming design that creates stronger, vibration-resistant connections in sheet metal
• Enhanced installation efficiency with No. 2 Phillips drive providing secure tool engagement and reduced cam-out risk
• Optimal material displacement from pointed tip and 15 TPI thread pattern for cleaner thread formation without chip removal
• Professional aesthetic integration with oval head design that sits flush while maintaining structural integrity
• Reliable performance in thin materials with maximum 0.025" drilling thickness capability for versatile sheet metal applications
• Streamlined procurement compliance meeting RoHS 3 and REACH environmental standards for global manufacturing requirements

Professional Applications & Engineering Value

These No. 8 thread forming screws deliver exceptional value in sheet metal fabrication and assembly operations. The Black-Oxide Steel construction provides essential corrosion protection while the thread forming (A/AB) design eliminates the need for tapping operations, reducing installation time and tooling costs. The fully threaded configuration with pointed tip ensures immediate engagement and consistent clamping force distribution. Engineered for 0.025" maximum drilling thickness, these Phillips oval head screws solve critical challenges in electronics enclosures, HVAC systems, and automotive panels where vibration resistance and flush mounting are paramount. The combination of 15 TPI thread density and 0.164" thread diameter creates optimal material displacement in thin-gauge metals without compromising joint integrity.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 8 screw size with 1/2" length and right-hand threading. The manufacturing adheres to A/AB tapping screw standards with 0.164" thread diameter and 15 threads per inch specification. Installation requires No. 29 drill bit (0.136" diameter) with 82° countersink angle compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for regulated industrial applications worldwide.
