S-95638A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Tamper-resistant T15 Torx drive enhances security and prevents unauthorized removal in sensitive or public-facing applications.
• 18-8 stainless steel construction provides excellent corrosion resistance and durability, ensuring long-term performance in harsh environments.
• Thread forming (Type A/AB) design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and improving pull-out strength.
• Fully threaded pointed tip allows for easy starting and smooth driving, minimizing the risk of cross-threading and ensuring consistent fastening.
• Rounded button head profile offers a low-profile, finished appearance while distributing clamping force evenly to prevent material damage.
• Optimized for 0.025" maximum drilling thickness in sheet metal, providing reliable fastening in thin-gauge applications without stripping or failure.
• Compatible with No. 29 drill bit (0.136" diameter) for precise pilot holes, ensuring accurate placement and reducing installation errors.

Professional Applications & Engineering Value

These No. 8-15 thread forming screws are engineered specifically for sheet metal applications, where vibration resistance and secure fastening are critical. The 18-8 stainless steel material combats rust and corrosion in industrial settings, while the tamper-resistant Torx T15 drive prevents tampering in public infrastructure, electrical enclosures, and HVAC systems. The thread forming (Type A/AB) design eliminates the need for separate tapping operations, reducing labor costs and assembly time. With a pointed tip and full threading, these screws ensure quick starts and uniform load distribution, preventing loosening under dynamic loads. Ideal for securing thin metal sheets up to 0.025" thickness, they provide a reliable, permanent fastening solution that maintains integrity in demanding environments.

Specification Summary & Compliance

These screws feature a No. 8-15 thread size with a 0.164" thread diameter and 15 TPI, adhering to standard inch measurements. The thread forming (Type A/AB) tapping method and right-hand thread direction comply with industry norms for sheet metal fastening. Manufactured from 18-8 stainless steel, they meet material durability standards and are suitable for use with a No. 29 drill bit (0.136" diameter) for optimal pilot hole preparation. While specific compliance certifications are not listed, the design aligns with common industrial specifications for quality and performance in fastener applications.
