S-90198A236 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial and marine environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time.
• Full threading and pointed tip ensure faster starts and deeper penetration for secure, reliable fastening.
• 82° flat head with standard profile provides a flush, clean finish when used with appropriate countersunk holes.
• No. 2 Phillips drive offers widespread tool compatibility and secure torque transmission during installation.
• Compliance with RoHS 3 and REACH ensures environmental safety and unrestricted use in regulated markets.
• Precision-engineered dimensions (No. 8 size, 0.164" thread diameter, 15 TPI) guarantee consistent performance and interchangeability.

Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws are specifically engineered for demanding sheet metal applications, where corrosion resistance and joint integrity are paramount. The thread forming (Type A/AB) design displaces material to create strong, vibration-resistant threads, eliminating the need for tapped holes and reducing assembly steps. This is particularly valuable in industrial and marine environments, where exposure to moisture, chemicals, and salt spray can quickly degrade inferior fasteners. The combination of a fully threaded shank and a pointed tip ensures rapid engagement and a secure hold in materials up to 0.025" thick, providing a durable, long-lasting fastening solution that maintains performance under stress.

Specification Summary & Compliance

This No. 8 x 3/4" tapping screw features a right-hand thread with a diameter of 0.164" and approximately 15 threads per inch. The flat head is designed with a standard profile and an strong>82° countersink angle for a flush fit. Manufactured as a Type A/AB thread forming screw for use in sheet metal, it requires a No. 29 drill bit (0.136" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
