S-90315A579 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 Stainless Steel construction ensures long-term durability and reliability in harsh industrial environments.
• Thread forming (Type A/AB) design creates strong, secure threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Phillips No. 3 drive provides positive torque control and prevents cam-out during installation for consistent, reliable fastening.
• 82° countersink angle with standard oval head profile offers a flush, finished appearance while maximizing surface contact for improved load distribution.
• Fully threaded shank with pointed tip ensures maximum thread engagement and holding power throughout the entire fastener length.
• Precision 0.242" thread diameter with 10 threads per inch delivers optimal grip strength and vibration resistance in sheet metal applications.
• RoHS 3 and REACH compliance guarantees environmental safety and regulatory acceptance for global industrial supply chains.

Professional Applications & Engineering Value

This 18-8 stainless steel oval head tapping screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations by cold-forming mating threads directly into ductile materials, providing superior resistance to vibration loosening compared to cut threads. The corrosion-resistant 18-8 stainless steel material ensures reliable performance in demanding environments where moisture or chemicals are present. With its Phillips No. 3 drive system and 82° countersink angle, this fastener enables efficient installation while maintaining a clean, flush finish that meets aesthetic requirements. The combination of fully threaded shank and precise thread geometry creates maximum clamping force distribution, making it ideal for securing thin gauge metals in HVAC, electronics enclosures, and automotive components where joint integrity is critical.
