S-90065A204 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without chips, reducing assembly time and improving joint integrity.
• Precise flush mounting with a standard flat head and 82° countersink angle for a smooth, professional finish in sheet metal applications.
• Optimized drive engagement using a Phillips No. 2 drive style, providing secure torque transfer and reducing cam-out risks during installation.
• Full threading along the 1-3/4" length ensures maximum grip and uniform stress distribution in materials up to 0.025" thickness.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe, sustainable use in global manufacturing.
• Compatible with standard No. 29 drill bits for easy, accurate hole preparation and consistent performance in repetitive assembly tasks.

Professional Applications & Engineering Value

This 18-8 stainless steel Phillips flat head tapping screw is engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. The thread forming Type A design displaces material to create robust, vibration-resistant threads without cutting, which minimizes weak points and enhances load-bearing capacity. Its fully threaded shank and pointed tip facilitate quick starts and even stress dispersion, reducing the risk of stripping in thin-gauge metals. With a 0.164" thread diameter and precise 82° countersink, it ensures seamless integration into assemblies, making it a reliable choice for HVAC, automotive, and electronics enclosures where durability and corrosion resistance are critical.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 8-15 thread size, right-hand threading, and full threading along the 1-3/4" length. It is designed for use with a No. 29 drill bit (0.136" diameter) and features a flat head with standard profile. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it meets stringent environmental and safety regulations for industrial applications.
